Wanted 68-71 Bellows style Cruise Control Servo
Looking for a 68-71 “bellows” style cruise control servo. These were used on both full size and A body cars. Also interested in other cruise control parts including the servo mounting bracket, adjustable rod and the 2 piece linkage that mounts on the intake manifold. alsutton@shaw.ca
Thanks, Al

AMC also got smart with the leak down issue with vacuum cruise control servo's and added that outer ring to improve sealing on the outer 2 plates. Although this particular servo shares the same diaphragm and front plate Oldsmobile used a different style rear plate that had a ball style connection for the adjustable linkage rod to snap onto. Oldsmobile also used a modified outer ring from 1973 till about 1979 to help stop vacuum leak down. There's a basic test in section 15 of the chassis manual to test a vacuum servo. You compress the servo and put your finger over the vacuum inlet. If the servo remains collapsed its functioning properly. If it expands back or leaks down you either have a tear in the servo rubber or a leak past one of the outer plates. If your outer plate is leaking you can take off one plate at a time and put a small bead of Vaseline in the outer edge and reassemble or use clear silicone. I digress...
Code 26 thanks for posting that one but I am looking for a 69-71 Oldsmobile style servo like the one Pops1958 posted. Pops1958 I appreciate you posting yours too but I think I will keep looking for one in better condition. Al
