Wow. Your original post was from quite a while ago. I hate to raise up dead threads and to be honest I missed it the first time around. Sad that you don't have a solution yet. I will do some research and see what I can discover. Here is hoping someone else will have an answer for you in short time.
I found these, hope they help.

This has been going on for quite a while. First, the 71-76 B-body cars use a different rotor than the 70-earlier cars, so I'm very skeptical of the parts shown in that link. I have not been able to find a replacement rotor for the 65-70 B-body cars anywhere and I've looked. No one makes them as far as I can tell.

Wow, Now I REALLY feel bad! In no way am I affiliated with crooks like these guys. See, you try and help someone out and what do you get? Actually, thanks to both Joe and Norm we now have more knowledge to protect ourselves from unscrupulous vendors.........................I learn something new every day.

[russell7088]

i called them last night after i read the message and got some one who sounded like they were at home with a bunch of kids running around under them and when SHE ( no offense to the ladies) asked me if i needed the rotors for the rear of my 70 delta 88 i said forget it i will call somewhere else
and hung up.


i hope someone out there can be of some help to me. right now i have some buddies trying to talk me into ordering a complete uppe and lower tubular control arm set with airbags but no one seems to know if the set up will work with the rear steer on the bigg 88

Have you looked at the following websites? I know they do good buisness. I have ordered from Kanter and Fusicks before, and I know alot of guys here on ClassicOlds recommend Rock Auto.

I've checked with Fusick - no luck. I would expect them to have the parts before the other two. Once again, I have not been able to find a source for these rotors. Bottom line is that few of the cars were made with disk brakes and even fewer survive now. The market apparently isn't profitable enough for vendors to make these parts.

[russell7088]

does anybody have one of those books that had all of the parts and peices that would exchange with other b bodies.. did the caprice police packages use the same rotor.

joe, sounds like both of us have searched everywhere. wish i could find the person who knows gm enough to tell us what would work.

I havent went to any cruises or anything cause i dont want to put it on a trailer to take it

if you do a search about gm b-body brakes you will find a couple sites that have an upgrade for the cutlass that uses the bigger b-body rotors. is that a 71 and up rotor

again guys thanks for ALL of your help i really appreciate it !!!

hey just realized i havent update where i live i am now in LEXINGTON Ky

I have a Hollander's interchange manual. It does not list a direct replacement. The 65-70 B-body cars used three different combinations of inner and outer wheel bearing diameters, which is part of the problem.

[kevinkpk]

My son repacked the wheel bearings on my 70 88 late last year, and told me the rotors were good, well, as time goes by I will have to replace them. So To the original poster (if you read this) when you find a source, please post it, I tried rockauto, seem to have everything else but the rotor.

[russell7088]

my rotors look like they have alot of metal left also but they are below spec to have turned!!!! they may look good but may be like mine to low to turn

[russell7088]

just did a search for gm b-body and found a list of the b- body cars thought it was interesting to know all the vehicles on this chassis

All of which unfortunately doesn't help much, since in the 65-70 time frame, the B-body cars used two different wheel bolt circles and four different combinations of inboard and outboard wheel bearing diameters. An Impala brake rotor may or may not fit the Olds.

[russell7088]

yeah i figured as much but was hoping that it might help a little also thought it was cool to see all the b-body that were somewhat common for the new guys also..

[J-(Chicago)]

I hate to be captain obvious here, but If you never turn your rotors they won't get out of spec. Unless you mess them up really bad by having a pad fall out or something. You'll get used to the hop if they get warped

I've had the same pair of rotors on a car for 9 years, just repack and re pad every year. Granted, it is not an everyday driver, but I assume an ol' 1970 Isn't going to be a daily driver either.

[russell7088]

i agree with that but mine have been on my car since i bought it in 1992
and dont know how long they were on it before i bought it

[J-(Chicago)]

One of our drawbacks of being Delta guys and not Cutlass guys. I hope you find something.
Perhaps we could modify an existing common rotor, and have it machined to match yours? I would challenge a local high school or college machine shop with this project. You could get your custom rotors, the teacher could get a free lesson plan idea, and the kids would learn.

[bcg88]

Have you tried Stainless Steel Brakes. They make a conversion kit for your car. I have a a '69 88 I am considering converting drum to disc. I talked to them some time ago and they have a kit for conversions. Perhaps they could help yo: http://www.ssbrakes.com/products/det...ight&year=1970

[aliensatemybuick]

I wouldn't doubt that a conversion kit might be made, but it would likely mean EVERYTHING from the spindles to the hub would have to be changed out. And one thing to consider is that the speedometer cable on these cars is driven off the driver's side wheel. Something tells me that functionality might be lost with a conversion kit if it were even available. Just one more complication...

That's right, the transmission I am using in my project was originally in a '69 Delat 4 Dr sedan and I now must figure a different way to operate the speedometer since the housing has no access for speedo cable drive and the spindle on the '46 has no hole for the cable (never mind the ratio is probably wrong for the actual meter itself).

[frdmftr]

At least the dialog is opening more options. This is a modification thats on my 'wish' list too.
Found this info for my 67 Delt 88:

Of special note: Does not work with power brake booster (kit comes with its own dual master cylinder)

Dear Santa..................

[Kennybill]

I am familar with the problem. I too have some of the big "Girls." I had a complete set of good disc brakes set-up but I sold them because I know no-one makes rotors. My drum brakes are rebuilt and they stop pretty good. My 98 comes through the traps @100mph's. You can change over to drum brakes. Least u can get parts and drive your car. I have an extra drum brake set-up. Ken

[russell7088]

i talked to you about the rotors you had but at the time i was laid off and cash fell short at the time i wish i had it the most.

the biggest thing i think of with the COMPLETE change (upper lowers spindles)is what about the fact that we are rear steer cars????

I am going to do some deep digging tomorrow on the phone maybe i will get somewhere with someone. I will definitly let everyone know what i find out.

[russell7088]

ok i found the ssbc brake kit and am considering it, kenny bill ill need to talk with ya see if you have any still.
also found a spindle in jegs that is set up for mostly mustang II uppper and lower but i am going into napa to compare ball joints and see if there is a possible way to use them they have a reversible steering arm for rear steer

kennybill if you have and drum rotors let me know how much thank you

what you come up with?

[russell7088]

haha read your post first and posted in it have not come up with anything it is going to be a project that will be lots of money and time but will end up with new uppers and lowers, spindles and an airbag set up. of course this will be custom!! went and found an interchange manual and all the way up to the frame is 69-70 ONLY we are screwed till it happens

Well I was trying to find a lower cost fix but looks like I'm going this route http://cgi.ebay.com/ebaymotors/ws/eB...AQ:MOTORS:1123

[russell7088]

that kit is probably for drum brake and i already have disc and the spindle is different hope that works for you

another thing is dont think that a 71 and up is the same because of the name and b body classification because they are not at all
