1967 vent/wing window adjustment.

I just spent several hours monkeying around with mine cause glass wasn't sealing to roof weather strip. I loosened all vent bolts up along with loosening screw on inside upper frame that squeezes vent frame. Move vent window around until glass seals to roof and vent frame seals to A pillar. I had better luck tightening screw on upper door frame first then slowly tighten other screws while checking alignment. You'll end up loosening retightening tugging vent window around many times until it lands where you want it.

Do you have '67 factory service manual? It can be downloaded for free.
