Years ago I convertiblized an o/t mini truck. I cut the window frames where they met the cut in the roof and at the back of the door. I. attached the removed frame to my metal roof. I left the forward part of the window frame attached to the door. It provided additional support to the window when up. The part I attached to the roof I moved up and back enough to barely clear the door glass. I used frameless window rubber (camaro/firebird) attached where glass met roof so it would 'wrap' over slightly when door was closed. Good luck. I'm subscribed and following along!
