Bill, the rear fuzzies have 2 screws, one on each end. The pinchweld has the tab the rear screw goes through. Ideally they should go on at the same time, but that takes a lot of hands
you can get them on seperately in either order I think, but the round trim of the fuzzie fits inside that little edge on the molding and the molding screw tab fits in-between fuzzie and qtr. I put the molding on first, then the fuzzie and it was a pain, but I think it would be a pain either way. and awl is your friend for locating the screw holes! If you are drilling new holes, make sure the molding is pressed down tight against the qtr when you locate the hole for a nice fit.
