Cruise Control Servo 1970-E1971 Olds Cutlass 442
Used Oldsmobile cruise control servo. This type was used on the 1970 and early 1971 "A" body cars. For restoration. The bellows look good but do not hold vacuum. $129.00, includes safe insured U.S. shipping. Check, money order, or PP. PM me if interested.

I have not personally tried it, but here's an old thread with a possible source for the rubber bellows. It appears a Jaguar part will fit.

A hard to find servo! You can take apart the servo and wash it in warm water with Dawn. Obviously you will end up restoring or replating the end plates but afterwards you can put a small bead of silicone in the inside edge of the servo rubber when re installing then leave it over night to dry. Finish up with McGuires number 40 rubber conditioner on the servo exterior. Will be as good as new and hold vacuum. Al

That is an incredibly wonderful find, Rick. The next step - I sure hope it is operable.
Best Regards,

The plating looks perfect, but I can see a vacuum tight unit would be a big factor in its function.
If you happen to run across what I am looking for please let me know.

Rick Hodgkins, they are very hard to find and the silicone should do the trick. Easy to test after the repair/restoration. Just collapse and hold your finger over the vacuum inlet tube and if it stays collapsed you are good. Al

I found a guy on ebay that rebuilds and sells and was very helpful.
But my message list is short now so finding him is tough.
He also made units from scrapped out transducers to couple the speedo cables in the event the transducer was not available.
I have one of those in the car atm.
