Bad "New" parts frustration.

Ugh...I don't even want to get started on this. It's unreal...the lack of quality control in car parts is just staggering. In the last year or two, I've sent back a couple whole carburetors (new ones, one flooding one half the cylinders only), points, fuel pressure regulators, a new radiator.......I try to rebuild old parts when I can anymore, but that's not always possible.
