The lower part of the frame was nearly all corroded away. the rusted and thin metal was all cut away. then a new door floor was fitted. The lower front corner was fabricated from two plates. (As above) Then the lower door skin was tacked in place before the skin lip was folded over . repaired GT6 door being hung to check fit. Upon completion, the door was hung on the tub to check fit and door gaps. The GT6 door seems to fit as well as it did before I took it off. So I hope there is wiggle room to taylor it after paint. The door primer After re skinning the GT6 door, it was skimmed with Upol gold stop filler the given a few coats of high build primer. Then the skin was flattened with 800 grit on a DA sander.
