I forgot to mention, probably the most important part of all this, is to make sure it’s aligned correctly!
Straight, and perfectly centered side to side as fits your specific Bronco.
Second, and as far as I’m concerned, equally important, is making sure the surfaces are sealed between the hinge and the body, and the hinge and the frame.
It’s nice when you’re finally finished. Bronco doesn’t end up with a puddle on the floor every time it rains.
Yep all this needs to be done before paint..........and door need to be installed and aligned,, My approch frame and hinge epoxy primed , plug weld frame to hinge,predrilled holes, 2 part seam sealer between and clamped plug weld holes clean . weld center out welder turned up minimal as possible weld time and let cool between welds,, fit align to body and doors , predrill screw holes as i screwed hinge to cowl,,,,,,, painted truck , windshield frame and hinge,, used 2 part panel bond { as there is more working time then seam sealer} between and installed screws ... not planning on taking off unless something bad happens ,,
