I just bought a 1995 Blazer, and i need a lot of parts..

How is the quality on Timken and Moog vs "Auto Extra" and what not, I guess I should steer away from those brands and keep to Moog and well known (for me atleast) brands?
What brands are good? I have gotten some "no-name" brand stuff from dealers here at home that does not fit at all..

I also need a new driver seat leather cover, is there some place to buy this still? Fender flares too. Can i only get AC-Delco parts at GM delaers?
