Firm Feel makes good parts parts and knows their stuff.
That said, in '08 when I rebuilt my Dart front suspension, I purchased a compete set of ball joints, tie rod ends, etc, and specifically said, I WANT MOOG.
"Sure, no problem" was the response.
I didn't realize it at the time, but I did not receive MOOG, or any other name brand. It was Chinese garbage.
All other components were top notch and it's entirely possible that they were bit by counterfeit parts just like the rest of us. But, beware.
