I bought a lower ,back part of the pass. side front fender, (between the door and wheel) it was the right gauge, and " looked good till we went to put it on," to preplace the bondo the previous owner had hidden in it.
My body man (friend) was excellent and did a bunch of reforming to make it fit right, I even had to weld, build up the back edge so he could get the gap right. He did an excellent job, and hardly had to do any skimming w. putty.
I think I only paid $67 for it.
