I'm finally getting around to reassembling our Long Neglected 66 Coupe, after being apart for almost 20 years.  I tore it down to repair a rusted cowl and wound up doing a full Mustang Plus suspension upgrade and body paint.  Point to note is that the car was on jack stands for most of the 18 years, located at the rear axle and front crossmember.

All of the sheet metal is original with the exception of the drivers door which was replaced sometime in the long past.  The car HAS been apart at one time for some reason, probably prior body work which MAY have included an attempt at cowl repair, I found way too much seam sealer in weird areas.  Being that it is near 50 years old, I'm surprised there wasnt more rust or collision repair.

As the photos show, there is an gap at the drivers fender to door, all the other gaps line up ok.
Drivers side fender gap to door.
The bottom of the door to fender gap is ok, as is the gap along the door bottom and rear.

The drivers door gap at the rear is ok too.


As a comparison, the right fender to door gap is ok.
Now, I feel I know what the general consensus will be, that the body is high center sprung causing the body to bow.  It has never had any support in the "A" pillar area for more than a few minutes, at least not in the past 20 years.  It has not been wrecked more than superficial parking lot damage and I really dont remember this gap when I tore the body down, but again, it was 18 years ago.  The only thing that I think MAY have any relation is I installed frame stiffeners but that is towards the center and rear.
