You probably made a good call on making your own outer door skin. I bought Brothers and they were 20 gauge with notches cut in the fold over edges rather being shrunk to form the correct curve. I've been trying to find time to blast my hinges so that I can repair a door with this skin, so I can't tell you much on what to look for in the way of fit. The door skin looks to have a bow in the skin, so they may have to be wheeled to get that contour right. If you only replace the very bottom of door skin, you may not have to worry much with fit. Some of the others may be able to help you on this. Do you have access to a bead roller to fold the new skin? A metal brake will get the lower edge folded, but you may have to improvise on front and back edge. The thing that concerns me is getting a dolly inside the door to hammer the spot welds as you go.
