Does anybody know where to get a cruise control servo for a 1974 Buick? From what I'm finding they look to be made from unobtainium.
Thanks for the link Korrie, but the one I need is from the stone age. No electronics, run by vacuum. The diaphragm itself looks right though.
Possibly, I don't know what one from a '69 looks like. Though hopefully it should be the same. It looks like the diaphragm from your link but on the back side is just a nipple right in the center to hook a vacuum line to.
Walter, mine is a bit different, the nipple comes out from the side. You are welcome to try it if you want. Just let me know.
If your talking about the part that bolts on the inner fender with the Speedo cable running thru it. I have always heard them refered to as a transducer. I will look as I believe I may have a couple but not sure original application. I also think the third terminal is for the cruise light on the dash and wouldn't be necessary to function.
