This video on Targa alignment is all in German (auf Deutsch) but the things they measure and processes they follow are great examples of how to trim all the various adjustments.

I have my driver side disassembled at the moment doing some of the same things. My manual crank window regulator has worn teeth at the top. Hoping I can find a welder locally who can mend those teeth.
Also replacing the door pockets, arm rests, replacing the door stay / reinforcing and replacing the front speakers (found the speaker loose and a huge hole from when the car was rebuilt years ago).
Parts were shipped by our host yesterday!! Isn't this stay home stuff great!! I've been putting off this project for 5 years!
