I've only reskinned two doors on a 64, but the process is the same. What I did was take off the outer skin and made a rough cut on the door bottom and then laid the new outer skin on the door shell and test fit. That way, you know the profile is right and you have a good baseline. Then I did the door bottom and made it fit the shell/skin profile and it came out pretty well, but the rear corner of the door bottom does rub on the rocker on one side. I've seen some guys pie cut the front and/or rear portion of the rocker where it radiuses up to meet the cab pillar in order to get more clearance.

But keep in mind, it's just sheetmetal. Worst case scenario, you have to get a new door skin or door bottom which are $50 and $20 and redo it but I don't think you will. From what I gather, you might have to cut the door bottom to raise it up or clearance a spot. It's weird that the window frame is tight though - are they the original doors? I can't imagine how the door opening would have shrunk or the window frame could have grown if they are the original doors. Either way, it's good that you caught it now rather than later as you haven't painted the whole door yet.
