Installed the passenger side door today noticed that top of door had about 1/4 inch gap larger than the drivers side door. It wasn't the adjustment just made that way from GM. I just happen to have a strap the same width of the difference so out came the MIG Welder. Here are the results the pics are of both door gaps to compare. I wouldn't have welded the darn thing on but it was very obvious and it look horrible to me. I am happy with it just more dang body work!
