Staring at fenders

I started working on the repro front fender that I bought at Hershey. The first step was to trim down the flange or lip where the fender bolts to the splash shield. They made it a good deal wider than on the original fenders. The next step is to see how much I can stretch the curved part of that lip to get it to the correct contour. If it won’t stretch enough, I’ll have to cut darts in it and weld in little triangles of sheet metal.
