I have a set of NOS door weatherstrips that I have installed on my 69 MACH 1 I am restoring, I fit the door first without the glass and my lines are good and the door shut perfect until I installed the rt. door weatherstrip that goes on the door itself. Now the door is very hard to close and I think most of the binding is at the front lower corner. I used a heat gun to soften and form the weatherstrip and that helped but it has a long way to go. Anyone have a similar problem and know of a solution. These are original doors, NOS weatherstrips and the hinge pillar and rocker/quarter panel are original and not damaged.
