Hi Guys, Little advise please as any one heard of any size difference in drivers door windows ? I got one of 79 camper (able to remove it though bottom of door) managed to fit it to my pickup, but cannot wind the window up without a great deal of effort its realy very tight . It starts to bend quarter window side runner as it nears the top also the top seems 8mm narrower . Any thoughts or advise welcome thank you.
