Check eBay and Amazon and you'll find many of them. Search as "cruise control servo".
Cardone is apparently rebuilding them so you might check Rock Auto or even your local auto parts shops.

Do you know if your issue is the servo unit or the transducer unit? As Emery pointed out, Cardone rebuilds the components. We purchased and installed the Cardone 36-102 transducer unit a couple of years ago and it completely restored the cruise to working condition again. I thought the problem was the servo but it held vacuum and is working today. The Cardone transducer units (if that is your issue) are available on Ebay, Amazon, etc. for around $100.

No, I didn’t say anything about the transducer. I was discussing the servo which is the rubber bellows that the chain attaches to.
