I bet there are some catalogs around here that may have them. I got a lot on Ebay when we did the 67 truck. Hubby also has a number of catalogs for aftermarket parts.
I am turning in as well. CM, you should have a number of, well, surplus parts between junk the crooked mechanic supplied and the things you order that just don't quite work. I am under the impression that crooked mechanics are cured of their wrong ways with junk parts enemas. It may work. If nothing else, it should make your friend feel better!
