Should you mount the windshield 1st, then the vent window assembly?
or
Vent windows, then the windshield?
Logic would suggest to mount the windshield 1st and work to the back of the car, but the vent windows don't appear to have a lot of adjustment fore/aft.
I would do the winshield, mainly since the door vent windows might get in the way, but either way doesn't really matter.
DO vent windows first so you can set gap for windshield. If it not right you can cause crack of doom. Most don't set gap right. Thet have it too tight at top of vent wondows. That on your center adjustment.
Do the windshield first the vents all loose until you alienment then with the door shut tighten windshield.
