Quarter Fitment Problem

68383gts,440abody and turbodart68,
Thanks for the responses. I first thought that maybe I should post pix of the area that I was talking about, but didn't. I hope that these help....
The first pic is the area where I am having the problem. The first hole above the outer wheel house/drop-ff seam has good contact. Between there and the corner, you can see from the shadow that there is reasonable contact along the inside edge, but the gap grows as you move toward the outside of the body. The second pic shows that there is good contact along the bottom side of the floor extension. The third pic is from the back side showing the gap in the corner. I have tapped the lip of the wheel well lip back so that it makes contact along the edge, but I will start to distort the outer surface of the quarter if I go much further. The last pic just shows the back side of the extension lip. The panel is welded right at the corner on the bottom side and I do not want to have to split that joint 'cuz it would likely be difficult to patch it back up. These are Sherman panels and were skins,not full panels.

As I tried to describe earlier, it looks like I could get away with welding along the edge in this area and try to plug the holes that I drilled originally to weld along this seam. I am open to any suggestions at this point. If you need another view, give me a holler and I'll try to get it for you. Thanks again. L8r
