Yes, but you're two years too late for this thread. Scroll up to Post #81. The most rare manual trans full size is likely the 1971 D88 - the last Olds full size available with a manual. It was a three-on-the-tree only and used the Dearborn (don't call it a Ford) toploader three speed. Keep in mind that 1971 was the first year for the new B-body cars, so that was a one-year-only column, pedal assembly, and clutch linkage and pedals. You can probably count the number of cars that came with that setup on your fingers.

I would have sworn the consoles were the same, but you are correct. The B-body consoles have a different part number in the parts book, and apparently were only offered in 1964-66 model years, and for 1964, the four speed was only available on the Jetstar 88 behind the 330. P/N 589590 is the console body for the 64 J88 only, P/N 386322 is the console body for the 65-66 full size, and 589085 for the 64-69 A-body cars. The die cast top plate is the same P/N for both A and B body cars. Even more interesting is that if you ordered the column shift three speed with buckets and console on the B-body cars, you got the AT console with a blanked off plate instead of the AT shifter.

Joe,
Yup 2 year old thread, but you guys have just saved me the pain & disappointment of buying A body parts on the Hope they were used in the B bodies, only to receive them, try to fit them and learn the hard way they’re not right. Great, if disappointing to be proved wrong sometimes.

A little embarrassing, but the spend, fit and learning of attempting to use A body parts as “close” would have been a huge bummer.

As always, thanks for passing along your knowledge and saving me the pain. ��

I only hope I can return the favor with what I’ve learned along the way.

Chris

There is another set up that is extremely rare. If more than the one I saw still exist. A 1973 Cutlass Supreme with a 3 speed on the column. It shows as being cancelled in the assembly manual. I did see a Brewster Green/white example in mint condition for sale once on ebay. What a novelty that would be to have! I remember my uncle showing me how to shift them, he had several "3 on the tree" cars, as that was the "standard" for many years.

On Saturday I went to the Cars & Coffee in my 71 98. There was 1 other Oldsmobile. A 1970 442. The engine was quite built with a radical cam and it had drag slicks in the back. When the owner removed the hood I asked him about the engine. The heads weren't Oldsmobile OE castings. I asked if they were Battens. They weren't, they were only Edelbrock heads.

I suppose Batten heads made for Oldsmobiles are quite rare today. They definitely fetch a high price. It's not a part made by Oldsmobile but there are many other aftermarket Oldsmobile parts that are quite rare. Didn't Edelbrock make intake manifolds for the 394 years ago?

When I was a kid many decades ago, my interest in Oldsmobiles was kindled by a guy who told me glory day stories about his 1962 Starfire which was set up with a cam,headers and intake. So, there was a time when that engine series was serviced by the local "Speed Shop". Remember those?

I know, I bought a shroud from you a couple of years ago for my restoration project. Searched for awhile till I found yours.

I thought the discussion was about normal production items? How could you find a W-43 crate engine when none were built for distribution?

Joe mentioned the W43 engine in post #12. Definitely a rare piece. I imagine they are in a museum somewhere.

Was reading through my 70 PIM the other day and noticed there are special part numbers for the hoses coming off the gas tank for California W-27 equipped cars. Try finding one of those NOS!

This may sound odd but the hardest 2 parts for me to find were:

70 rear tailight housing (the metal part that bolts to the back of the bumper that holds the lightbulb)
68-72 windshield wiper cam (not sure if what it's called but the part that the chrome arms attached to that "breaks" off if your wipers get stuck while running.

Again, people are confusing availability of replacement parts TODAY with parts that were rare even when new. ANY 50 year old NOS part is rare today. Those Calif-only W27-specific vent hoses were probably rare in 1970, however. And rarity of hand-built experimental parts is also not particularly unusual.

Are those just 3/8" rubber fuel hose or do they have specific ends or markings?

This trim? From my 70 S. I can say I haven't seen another with it. Pardon the missing piece of vinyl.

I have a set of 15" SSII wheels with bolt-on center caps. I believe these were unique to 1974

Not necessarily rare, but they are getting hard to find these days. They were available from ’73-‘74. I’ve got them on the front of our wanna-be wagon. I typically buy them when reasonably priced.

Here's one courtesy of our own John Herald. The oil filter adapter from a FWD Olds diesel. I've seen the RWD versions (and have one) but the FWD versions are pretty rare. Yeah, those are oil cooler fittings.

The 69 disc compatible SSIs were a 1 year option. All chrome like their predecessors, but could do disc brakes like their successors. Quickly overshadowed by SSIIs.

That's quite a rare piece!

So the Olds diesel used an auxiliary oil cooler mounted in front of the radiator?

Actually it was in the radiator like the trans cooler.

So here is a twist on the answer.

Although most every car left the factory with one of these, there is only one of each in the whole wide world.....talk about a rare part.

Your car's VIN tag....

So is this a candidate for rarest part(s). The MISAR system (microprocessed sensing and auto regulation) ignition timing system introduced on the 1977 Oldsmobile Toronado?
I have hunted high and low for years and cannot find any parts for this unique control system or anyone that can rebuild them.

There were 36,000 Toronados built in the 1977 model year alone, every one of them with a MISAR system. Not exactly rare. The fact that you can't find any 45 years later doesn't mean they were rare, it just means that none survive and there is no business case for a vendor to reproduce them. Try finding front fenders for a 1980-1990 Custom Cruiser. There were a bazillion of those made. Most have been crushed now. Try finding a speedo cable sheath for a 1965-70 Olds full size. Try finding anything for my 62 F85 wagon. Don't confuse survival rate with something that was rare even when new.

How about a 1990 Custom Cruiser Multi-function Chime Module for the Y67 Reminder Package option? The part number is a one year only part and mine doesn't work and none exist on the internet.

There was an article on Hemmings.com recently that dealt with just this subject .
It dealt with the un-availability and un-repairability of the many electronic gizmos in 1980's and newer cars .
Many of which are essential to the vehicle's operation .
The conclusion was that this problem may lead to these cars falling into two catagories .
Museum pieces or scrap .

Olds64, maybe but either way I can't find one. It doesn't stop the lights from working, just no chime to alert you to them.
Charlie Jones, hopefully not, I like driving it and it's my son's car.

It is in fact a one year only option (Y67) and only for the 90 Oldsmobile CC... The part was discontinued Nov. 98... Buick, Chevy, and Pontiac did not offer the Y67 option, not to say however that they did not have have an alternative type package with a different option code using a different module... Have you tried using the standard (Non Y67) module from other year CC/88/98's??? If so, what were the results???

Good question, but I've owned one of each (and sold them both at the G'burg OCA Nationals). The tailgate came factory on the 84 CC that I had. The hood I bought from C-List. Usage was random.

I have seen 2 hoods but never a tail gate and only know of you and one other person that had one, which I tried to buy.

CRUZUN66, No since the lights work I don't want to introduce something that shouldn't be there. Plus 90 is the only year with the passive seat belt warning.

Rear End

By far, the 1970 - 1971 years if you could even find one out of the car would be the W-27 spec all aluminum rear end and cover option.

Oldsmobile surpassed most muscle cars in 1970 with the W27 aluminum differential housing and cover option in the 442. If you find one on a W30 or W31 from either 1970 or 1971 you would have found a big gold nugget. I prefer the Platinum GM paint code myself.

I'm not going to say that I am unfortunate not to have this on my 1970 Platinum GM code rotisserie restored 1970 W30 442. It was an option back when that few would pony up the probably $275.00 extra for. If we only knew then what we know now?

Nonetheless, after 10 years of rotisserie restoration, I don't endeavor drag racing my beauty. The rear is a 3:91. Yes it's a real W30 without A/C or brake booster. Let's see how many of you can guess why a real 1970 W30 did not come optioned with either item?

Hint: this car was factory optioned with the 375 HP camshaft.


Doc.

I would think the RWD oil filter adapter would be more valuable since folks sometimes turn a DX block into a race engine. Then again, the oil cooler adapters might not even be used by racers.

Rare doesn't mean valuable.
