Cruise control servo

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.

 

I've heard Rock Auto carries rebuilt ones

HTH

 

That is a fake Chinese scam website. Notice the .XYZ url?

 

I see .htm, not sure what you are talking about. I gave a link to A1 Cardone.

 

...And it actually works, it goes to A1 Cardone.

 

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.

 

I may have one from a '69. Will that work?

 

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.

 

I believe the 69 only has 2 terminals and the 74 has 3 Terminals or vice - versa

 

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.

 

I have one I took out of a big car in the 80's. I think it was mid 70's model. Also have the module
