What exactly is involved in adjusting side glass on a ‘70? Do I work in the door glass and then the rear 1/4 glass or the other way around? What adjustments need to be made exactly? One side is far off while the other side needs a few tweaks.

Yes, I know the 1/4 glass chrome trim and rubber also needs to be installed.

 

Get yourself a body service manual to help. If I remember rear quarterwindows first before the doors.
