All I can say is "my experience." I should not have to go into a parts store and use a crowbar and a shotgun to get quality parts out of the guy behind the counter. I've had a fair amount of bad luck lately, with some parts INCLUDING NAPA.
Leaking around here somewhere is a guy with a 440 conversion who is "going through" Moog idler arms. He sawed one open and it has PLASTIC bushings which are melting, evidently.
By the way, you are talking to a guy who in a "previous life" sold auto, truck parts and heavy hardware in two different stores for over 15 years up into the middle 80's
