OK, by popular demand, here's the list of motor mount applications by frame brackets. This applies to all 1964-1990 Olds V8s (as usual, excepting the 1964 394). The use of a big block or small block does not matter. All that matters is that the rubber motor mount matches the frame mount. Also, please see the notes below the table.

A-body, G-body

1964-1968 frame mounts (all) - use P/N 2261 motor mounts
1969-1972 SBO frame mounts - use P/N 2261 motor mounts
1969-1972 BBO frame mounts - use P/N 2328 motor mounts
1973-1988 frame mounts (all) - use P/N 2328 motor mounts

B-body, C-body

1964 frame mounts (Jetstar 88 only) - mounts are unique to this year and currently not available
1965-1970 frame mounts (all) - use P/N 2262/2263 (RH/LH)
1971-1990 frame mounts (all) - use P/N 2328

X-body

1973-1974 frame mounts (all) - Use P/N 2328
1975-1979 frame mounts (all) - use P/N 2328

Notes

1. Motor mount applications ONLY apply to cars that have same year frame mounts for OLDSMOBILE motors. For example, from the mid-1970s-onward many Oldsmobiles were built with motors from other GM divisions. You must change those to the correct Oldsmobile frame mounts to use the motor mounts listed here.

2. Diesel cars have the driver's side frame mount located forward of the normal location. The motor mount was similarly moved forward using an adapter bracket that bolted between the block and the motor mount. This was done to clear the larger diesel starter. If swapping to a gas engine you can use these parts as-is or relocate the frame mount rearward to the gas engine position and delete the adapter bracket.

3. The 1964-70 B/C-body cars and the 1973-74 X-body cars used the two forward motor mount bolt holes of the three on each side of the block. All other applications (except diesel driver's side as noted above) used the rear two bolt holes on each side of the block.

Edit 4-5-11: Added 1973-4 A-body mounts

Thanks Joe

Joe,

Please explain in simpler terms, I still don't get it.


(Just Kidding)

Thanks Joe,

Do tell..........what number of times explaining it put you over the top.

atkinsom

Perfect...thank you very much

Cratethis

Good work Joe


Just wait... it will get asked again.

Jamesbo

Joe sent me the A body on Mimeograph paper [ A while back]

Beob

Thanks very much Joe, I might be the one who prompted this thread

joe_padavano

Updated original post to include info on 1973-74 A-body mounts. I'm still looking for the 73-74 X-body info. If someone with one of these Omegas has that info, I'd appreciate it.

ROCKET VAPOR

Joe, who is the manufacture of these mounts, and where is the best place to find them?

joe_padavano

Anchor and Pioneer are the two most common sources. Both use the same part numbers. Both are Chinesium. I usually get mine from RockAuto, but most auto parts stores sell them as well. Do NOT use the catalog lookup feature for these, as in many cases the listings are incorrect. Witness the recent threads. I just use the Part Number Lookup function on RockAuto's website.

joe_padavano

I should add that the Anchor/Pioneer mounts are not the ones you want to use for a factory-correct restoration. In that case, I'd go with mounts from one of the Olds specialty vendors. On the other hand, for a driver, these are perfectly adequate and very reasonably priced ($8.42 each for 2261s and $5.75 each for 2328s at RockAuto - though these prices are about double what they were last year!).

1969w3155

Printed and put in my "Olds" binder. Thanks, Joe.

ROCKET VAPOR

Great information, Thank you Joe!!!

I was going to get some from Supercars Unlimited for a correct restoration of a '70 442. Do they still have the correct rubber motor mounts for my application???

geckonz08

Joe is hard to wind up but this one gets him .

good sticky

joe_padavano

Their website says that they do. Note that they list more than just two part numbers. The differences are most likely in the rubber stiffness for NVH tuning. Dimensionally, they should all match either the 2261s or the 2328s.

ROCKET VAPOR

Thank you again Joe for the information!!!

I will now order these motor mounts from Supercars Unlimited, so I can get my engine back up to the proper height.

Hopefully with these proper mounts and me finding the correct 19" fan blade, I can finally get the fan shroud installed.

Dapapadon

Now that's the best idea I've heard in a while. I tend to copy & paste stuff. Or bookmark links. Then I have trouble finding them when I need them. Think I'm going to start my own binder. Thanks!

And a big "THANKS!" to Joe too.

Don

1969w3155

I have been doing that for a couple of years now, ya never know when you might need the info, and it does come in handy. I have three 3-ring notebooks with Olds info, paint samples etc.

Cratethis

You also never know when that link is going to get broken, or the information gets taken down and lost. Sometimes you never can track it back down.

Dapapadon

Yep, you guys convinced me. I've got a binder, some dividers and found my 3 hole punch. So Joe's first post above is officially the first entry in my new Olds reference "manual" (binder).

Thanks again, Don

Chumley

How do you verify what FRAME mounts you have? Is it likely these could have been changed when a replacement motor was installed?

joe_padavano

Excellent question. I was wondering when someone was going to ask it.

This should help:

jankyrre

Hallo.

Are you sure your listing above are correct.It says motor mounts 2261 for a 68 400 engine,if I understand it right.
Bought a pair of motor mount from Fusicks for a 68 442 (400 engine)
The catalog says 1109 for this car.
The ones I received have the stamping 2261 on them.I do not have the boxes the came in.
The issue is that the original mounts(probably) do not look like the 2261 style
Different design and thicker steel on the originals.
The will probably fit though.
The question iso I have the correct ones?

joe_padavano

P/N 2261 is the Anchor (and Pioneer) part no. Fusick has their own catalog numbers and other vendors will have their own numbers. There are only two different mount designs for the A-body cars, the 2261 and 2328 as noted above. The 2261s look different from the OEM 1968 mounts because prior to the 1969 model year, all Olds motor mounts were simply two pieces of metal with rubber between them. GM had a major recall for broken motor mounts in the 1960s and all mounts since then have the "fail safe" interlock to prevent separation if the rubber delaminates. The 2261s have this feature but will fit in place of the OEM mounts.

jankyrre

Hello and thanks for the answer.

The issue for me here is if Fusick did send me the right mounts.
I know I ordered mounts for a 400 engine and that is also what the invoice says.(item 602-1109)
I do suspect what I recieved are mounts for a 350.The boxes were removed in the US before shipping.The mounts are stamped on the side with the text"ANCHOR KOREA 2261"

The attached photo shows the new one to the left,the original on the right side.

DSCN0933.jpg

TripDeuces

I think all you need to worry about is if there is a height difference?

joe_padavano

Please go back and read the very first post in this thread. BOTH 350 and 400 use the same mounts for 1968. You have the correct mounts. You just paid way too much compared to what RockAuto sells them for.

68442CONVERTCO

FYI
Anchor 2261 $3.39 at Advance Auto Parts and shipped to store overnight.

joe_padavano

OK, I didn't see the attached photo when I originally responded from my phone. The "original" on the right is not an OEM mount in any case. The OEM mount in 1968 did not have the interlocking fail safe feature. This one does, so it's been replaced at some time in the last four decades. Not surprising.

The Korenium mount you got from Fusick is interesting from the standpoint that it appears to be made of thinner metal and to have larger bolt holes, presumably to allow looser manufacturing tolerances. Oh well...

On both mounts the interlock feature is the raised piece that is sticking up from the rubber between the two vertical metal mounting tabs. Oh, and the frame mounts you have are the correct ones for a 68 442 that accept the 2261 mounts.

mac61891

This post is incredibly valuable and I greatly appreciate the info. I am preparing to install a 403 into my '84 Cutlass. Was a 3.8 originally and it was locked up at purchase. I shoved a fuel injected SBC into it since I had it lying around. I am ready to go back to OLDS Power, now, but lack V8 Frame mounts. I know what cars I can get them on, but am having trouble finding some that are not in use. Any ideas, or would someone have a set they would be willing to sell?

joe_padavano

All 1978-1988 A/G-body and 1977-1990 B/C-body RWD cars with Olds motors use the same frame mounts. If you're looking in wrecking yards, check any GM B-body wagon, especially in the late 1980s. Nearly all of the wagons came with 307 Olds motors (such as my 86 Caprice wagon). These frame mounts will fit your G-body. Note that the frame mounts are RH/LH.

Bitburger

I just got back from motor mount shopping. Advance in my area does not list Anchor mounts as available in any of the numbers 2328 2261 2262 2263 as being available.

So I next went to O'Reilly. I was told and shown on the screen that the same numbers applied to the following applications

PN 2328 350 for a bunch of years and 455 for 1971 Motor side mount
PN 2261 They did not list
PN 2262 68 - 76 455 Motor Side mount right
PN 2263 " " " " " " left
Pictures on the O'Reilly computer screen showed these mounts as all motor side.

The counter guy called Anchor and was told that Anchor did not make the any frame side mounts.

So I ordered PN2262 and PN2263 for $6.39 each and will have them late tomorrow.

So now the problem is obtaining the frame side mounts to put my 455 into my 69 Cutlass Convt.

Based on the pictures above I know which frame mount I am looking for. BBO Type II . So if Anchor does not make them who does other than Year One or Fusick and what part number am I seeking ?

Since they are steel only (no rubber on the frame mounts)a used pair
should work fine.

joe_padavano

Well, whoever you dealt with is an idiot. Adavance Auto's website shows 2261s available for $3.59 each and 2328s for $6.49 each.

http://shop.advanceautoparts.com/web...earchTerm=2261

http://shop.advanceautoparts.com/web...earchTerm=2328

And those applications would be completely incorrect. Did you read the first post in this thread?

Which is correct because the metal frame mounts do not wear out.

At which point you will return them because as pointed out in post #1 in this thread, those mounts are for 1965-1970 full size cars ONLY. They will NOT fit any A-body frame mounts because they have threaded studs that fit into holes in the frame on the full size cars. Here's a 2262 (from the Advance Auto website, I'll add). Note the stud sticking out of the bottom.



Why are you looking for frame mounts? Again, PLEASE go back and read post #1. If your car currently has the stock small block frame mounts, return the motor mounts you bought, get the 2261s, and bolt the 455 into place.

Bitburger

Joe,

Okay, so then the 2261s would work on both sides ( Right and Left) on the 455 and my current small block frame mounts would receive those 2261s and bolt right up ?

The Advance guy typed in Anchor part numbers and applications and while the word Anchor came up on their screen it said not available. I'm wondering if it is a store location availabilty thing ?

Thanks for clarifying

joe_padavano

From Post #1 above:

You can go to the Advance website and order the parts for delivery to your local store. Alternately, go to RockAuto and have them delivered to your doorstep.

Bitburger

Thanks again Joe. I ordered the 2261s from O'reilly same price as Advance.

Brad

naphtali5725

best place to get frame mounts? part numbers?

joe_padavano

Frame mounts don't wear out, so most parts sources don't sell them. Some of the repro houses (Fusick, others) sell repro frame mounts. Again, unless yours are missing, you don't need to change the frame mounts for an engine swap.

naphtali5725

yeah, i have a 86 chevy c10 pickup that i am dropping a 455 in, so i was wondering where to get frame mounts, doesn't matter what they are out of, i can bolt/weld them in the proper place, so fusick has them?
