Rear quarter window adjustment 1969

Can someone advise on the correct order to adjust the mechanism for the quarter window… What does the screw with the allen head do? Thanks in advance…serves me right for taking so long to re assemble and not taking pictures.

Get yourself a copy of the shop manual,volume 4. It will tell you everything you need to know about adjusting the windows. The whole set of 5 volumes are a great addition to have on hand.
