I bought the whole door kit. I still need to buy and do the hatch weather strip.
I put off doing the window channel run and felts because I thought it would be a real pain, but it wasn't nearly that bad. You don't have to pull the glass. The door weatherstrip is crazy easy, just pull the trim panels (loosen the back panel) and the old just pulls out and you push the new one on. I should done all that as one of my first jobs, it would have me happier with the truck sooner. It went from sounding like it was falling apart to a pretty decent old truck.
