Have a 2001 SB 2500 EXT Cab with a Glasstite "Targa" model cap. Destroyed the back window/door which is a one piece glass unit. Spoke to Glasstite, quite making them in 04', tried several dealers and they knew as soon as I asked about a Targa what I did, and said they didn't have any back windows left. Tried an auto glass dealer, they tried their contacts, nothing. Be better to just buy new/used cap over custom making a new window. Anybody have an old/wrecked topper I can score a window from, or someone know somebody who can help me out?
