What Bill said, Chicago Carburetor is a good source for SOME parts, but many of the parts often needed in a build are not available. You can also try Holley's Custom shop, they sell parts too, same deal though, may not be in stock and you might have to wait a LONG while waiting for them to make another run. Bills repair method works very well FWIW.

Thanks everyone, I have been in touch with 62 maxwgn. very helpful and knowledgeable.
