There is no one single bolt for the window adjustment. Search in here. There is a detailed thread somewhere on how to adjust your glass. It is slow tedious work. In case it wasn’t obvious, I should also clarify that to adjust the front and rear brackets on the opening you have to remove the trim covers. I forgot about the door adjustment alignment. Definitely get your gaps right and the door properly aligned before adjusting anything else. Glad I helped. There are A LOT of different adjustment points to get the tops to fit right and the windows to open and close properly. You also want the tops tight enough that the dont vibrate loose at highway speeds or rattle. Good luck!
