I was in a bit of a hurry when I dashed off my previous reply, but let me expand on that a bit: I'm a journeyman Diemaker, and I was also a press operator at times,too. As an example, I ran a press making a steel "bowl" for a transmission-it was about 12" in diameter, and maybe 2.5" deep-the press I ran was an 800 ton press, and the part was somewhat thinner than a model A fender. That press was two stories high, and maybe 20 feet long. That was one of our smaller presses-we had them up to 4000 tons-as big as a house, for sure, and three stories high. A part like a fender is Drawn in a die-basically held at the edges and stretched over the form of the die steels-so once you have formed the basic form of the fender, you still have to trim the uneven edges before you can proceed to the next operation, which would probably be rolling the edges. That fender die is also going to have to have accurately located details to produce the headlight bar mounts, and other closely-toleranced holes on the edges. The die sets are of course, going to have to be quite a bit bigger than the fender itself, with the details made up of specially coated die steels such as D-2-so many things to consider, but I've just touched on them.
So you want to find a factory in a foreign country to do it? No matter where you do it, they will still require skilled Diemakers and machinists, expensive materials, and enough press capacity to do it. Once they get the dies built, there will always be considerable try-out time and modifications involved before an acceptable-to-print part is produced.
I honestly don't think there are enough Model As being restored these days to justify the staggering cost.
