Agreed with Bullitt. Depends on what you need to get. I have had good luck with Summit and LRS since they have a bunch of stuff that I might need - I am all about one stop shopping.
I usually order from LRS (50resto), but they were out of a clutch cable kit I wanted. So I called CJ Pony Parts and am giving them a try. I hope it works out. The guy who took my order pretty much rushed me off the phone. I hope my order goes through ok.
