I spent about 3 hours refitting and welding in the panel Cecil and I made on Thursday. I had left a bit of the rain channel so the quarter panel wouldn't move before I welded in my patch... Well after a ton of fitting with the decklid and scratching my head, I figured out that the quarter might have been welded in wrong by the PO's body butcher. With that in mind, I cut the channel and freed the quarter up to move around a bit. I was able to take out some of the pie shape in the top of the gap and also I leveled up the quarter and decklid. After that was done, I welded in the panel and it looks like I haven't got a perfect gap, but it's about 1/2 way there... I'll either lead it in or hit it with the body filler. I doubt I'll cut any more on this panel, it's already been through hell and back.
