Couple of questions on sheetmetal/bodywork

First, good luck getting AMD to give a return, or refund. I had a problem with their bumpers, and they kept dragging it out until I just used them. As Treblig said, splitting the panel, and raising it seems to be one of the better ideas. I remember seeing it done on one of the car shows, but I can't remember which one. As was already said, start with the door hinges first. Then line up the door to the rocker, and to the quarter panel that's been mostly attached, except for the area needing to be modified. Then split the quarter to raise it in position. Expect to make the cut longer than you think. You don't want to kink the panel pulling up on it. Then weld in your filler piece. Some bondo will take care of minor issues.
