What difference does it really make anymore? Are you 100% SURE all the ones you posted are made here? And since when is MADE IN USA really 100% good anymore?
Went to NAPA for some new front brake rotors for my Ram because they was warped bad. Dodge had a problem with their Ram rotors warping (long story). The NAPA guy told me I had two choices the rotors made in the USA or the rotors made in China. He said if I bought the USA ones I would be in here next week complaining about warpage. I bought the China ones and they have been on there for at least 10 years without issues.
First thing that came to mind seeing your post..lol
