The panel I had was a full bottom window channel to trunk seal channel. It had folded edges on the ends that spot welded to edges that were part of the tops of the rear fenders. Then seam sealed from the corners down(except on verts). If the corner are as bad as mine were the rust and rot extended up the sides of the window channel and those had to be repaired before the new panel. Also the bodyman was giving me grief about the rust that I didn't take care of before I delivered it to him. He must have sandblasted all of it and rust morted before he put the new panel in because I still have sand raining into the trunk when I drive the car. That said, he did an excellant job on the installation. One thing I haven't dealt with yet is the reveal moulding. After all the trouble to replace it I didn't want drill new holes in it. After all that's why I replaced it in the first place. I thought I could just set it in some silcone to hold it on but the curve of the moulding is more severe than the panel and it is going to require drilling and installing the rivits for the clips. If you end up needing some, I have extras. I bought 100. It means pulling the window again so I figured I'd wait for winter. A real PITA. This wasn't the first time I've had the area repaired. Last time it was weld and fill. Lasted about five years. If it's not done right you'll be doing it again.
