I found a little old Motorcraft Parts and AC Delco parts wholesaler by accident. They actually distribute to dealers, no advertising, but will sale to a few individuals on a cash basis. They said there were tons of places like theirs in the 60's and 70's but there are not many left now.

The prices are cheaper than the dealers, but I am sure not as cheap as when a dealer buys from them.

Does anyone else have these in their area?

 

No, but it would be cool. I can't say I have seen one, maybe just the AC delco on a very small scale.
