I have purchased about 90% of the parts needed to do a frame up on my 1952 3100. I have used just about everybody. Problems occasionally occur with almost all of them and all have been resolved. It greatly helped that I have ordered things well in advance of needing them. That said, I pretty much don't even look anywhere but American Classic and Jim Carter. I wouldn't hesitate to buy from almost any other common vendor but all things considered- price, quality, in stock, service, I have had the best luck with those 2.
