If Alfaguy can't help you I have a full set of alfetta calipers from the 79 NJ Alfetta sedan. They may need to be rebuilt though. I would say I could be your 'last resort'. Also, I am close (Hagerstown, MD) in case you wanted to check them out first. Actually, they are still with the rear dedion and transaxle sitting in my garage. The rest of the car is at the crusher. Anyway, let me know if Alfaguy can't help you out.
