We read your question about the door, the glass and the weatherstrip. It doesn't really matter how you do it, the one problem you would have with the door on the truck is the weather stripping, you'd have a problem putting the weather stripping on because it to close to the cowl with the hinges. So you need to have the door off for that part. The window and the other parts can be installed on or off the truck. Make sure when you start working on that window stuff make sure you give the nuts and bolts a good soaking of Liquid Wrench because they are going to be rusted. (Take your time).
