A little. Got the back corner in place:
Welded it in, knocked the proud off the welds, and laid the center section in place.
Still a LOT of work to do on this fender...on all of them actually. The center section fits pretty well but putting it in place will be non-trivial because of the tipped trunk opening flange.
The two rear fenders will NOT be welded together but rather have a seam in the center. My idea is that the seam will bolt into a piece of aluminum INSIDE the trunk and there will be a piece of trim that covers the seam.
Also, my current thinking is that there will be a recessed license plate area in the center bottom. The exhaust will exit in the center also. Two pipes side-by-side.
