Hey All, I have a question about the back glass for a 1988 Ram 50 ext cab. I'm looking for a slider window and need to know if a window from a regular cab will fit an extended cab. I ordered one from a salvage yard a few years ago and just got around to having it installed and it won't go in. It's like it's a hair too big. The gasket is new and works with the fixed window. So, I'm looking for another window; even an aftermarket would be fine. I found one online but it says vehicle specific and lists the regular cab as the only option. Hence my query.
