Hello fellow M20A owner. I have owned several Mooneys including a 1962 C, a 1960 A, and currently own a 1979 J. I am currently helping my son get a 1960 M20A N8389E back in the air. I ferried it 800 miles home in November, so it was a good foundation to start with. You probably have this figured out by now, I can help with firewall locations of cables and other components if you still need it. I see your prop governor cable is not routed where mine is but should work ok. I would appreciate a call, since we are currently installing a new interior and have a question about the rear seat back. The pins fit is the base perfectly, but the upper attach points don't seem to line up. Please call is you get a chance. Gary 608 334 0051
