Hi all. I am in need of a vacuum operated expansion valve for a 1964 Buick Wildcat with the 401 CID V-8 engine. I have no idea where to look for such a part, can anyone offer any help?

NOTE: This would probably belong in a "Parts Forum", but there doesn't appear to be any forum like that on IATN so I went with this one as next best fit.
