On my '51 pickup- the gap is too tight at the lower part of the trailing edge of the door. Leading edge is fine and for some reason up high by the window frame the gap is a little too wide (but I'll live with it). I've been told a couple different ways to take care of adjusting the gap but I've not done it before and would like advice on the Real way to do it. I'll post a couple pictures but I know it's hard to see. Dark garage and black primer at the moment. As usual, thanks in advance for any suggestions.
