Inner roof structure and drip rail flange coated with two coats of SPI epoxy.






Roof skin mocked up to roughly mark the back edge for trimming. I cut out the original flanged seam, then clamped the roof back in place and scribed the edge of the roof skin for trimming with hand shears... good forearm workout.






I also checked the fit across the sides and front while mocking up the roof skin and made notes to shrink/stretch the flange to fit the drip rail contours better. Lots of on/off and small adjustments to the the shape corrected.




I noticed how rough the pinchweld was on the last '66 F100 we restored, and this one was no different. Most spotwelds were twisted and the edges of the flanges were very rough and uneven. I flattened the twisted areas with a hammer/dolly and ground the edges even and smooth with a 2" grinder. Also slightly rounded over the edge so installing the windshield will go smoother.

The A-pillar to upper windshield frame fit was really bad, so I made a relief cut to allow for reshaping, then welded up the cut and seam.














Same issue with the lower seams.
