Thanks for the interest in my post. All I need help with is door glass. Pix may be attached, not sure camera batteries low. According to my build manual, the door glass is contoured. Looks to me like flat glass will work? The manual lists five different components: window support, adjustable window channel (lt/rt specific), regulator, felt, and glass. The integral rear channel in the picture measures 11/16" wide, 1/2" deep. None of this seems difficult, but all the pieces have to fit each other. Maybe I am being too picky, but if one part is out of spec, I'm going to have problems.
