Yep pic #2 is what I was trying to get at on page one
I like what you are thinking with your layed out door you are drawing on BUT, keep in mind were your top edge of the door is in relation to the door hinge pivot. Any part of the door that is in front of that pivot point will swing inward when the door is opened and if this part of the door happens to be the top of the window post (pic #1) the door will bind up and not open. This is the reason for the filler pieces in most crew cabs. Also I have looked at the door hinges on a 65 (not sure if they are the same or not) that I was working on for a co-worker and I think they will work for a rear door if the jamb and door are set up right. On the 68 crew cab that I built I just used the stock burb rear door hinges and reworked the jambs and it turned out great.
