You don't have PMA.

I cannot buy a Gates belt and put it on my Piper, but I can but a belt from
Piper that they bought from Gates, and put it on my plane. Nobody could tell
the difference, because there is none. That doesn't make it legal.

Same holds true for the u-joint holding my yoke together. It's not legal to
put it in the plane unless Piper has blessed it first (with their invoice).
