I've got a driver side piece coming from Wolf next week, will let you know how it works out.

For passenger, I just cut off the bottom 6 inches of an SC dogleg, same with my 69-73. Edge to edge, the piece fits perfectly. But the foldover seam on the SC piece is 2mm narrower than on the fender, which means the mounting spine is 2mm off. I'm sure I can massage it over and will be fine, but a good reminder that these cars are all made by hand.
