All the windows work and are adjusted, doors close nicely. I finally installed the exterior door handle linkage and lock hardware. Waiting on a new pair of long outside door handles before I install the interior door panels and finish the interior.
Pulled the car out today to work on the lights. Once I replaced all the bulbs, everything with the exception of the reverse lights worked.
The reverse lights took a little de-bugging. I found that if I jumped the two terminals, the lights worked. So that meant the switch had a glitch. Turned out that you have to adjust the switch on the base of the steering column by loosening the 2 mounting screws and sliding the switch to the left or right so the backdrive linkage activates it at the right spot. (The 72 used a reverse light switch on the steering column - no switch in the trans like some models). Works great now.
Assembled and installed the mirrors. (Thanks Charley for the reference photo from your 70 Z on the unpainted mirror mounting screw.)
