Ive been told by a body shop, or a guy who has done this before..why do it? it would take less time to just goto arizona and buy a old land cruiser. Problem is, I do not have 2,000-5,000 dollars for a replacement truck, airfare, hotel and food cost and fuel to travel 1,500 miles, or border taxes.
The thing is, I don't care. My labor is free. I am bored If I am not working. If I have the tools, I can do it. I never stop until its done..or very tired
It is also a learning experience. If I did it once, I would learn alot from it. Yes, I would need a shrinker stretcher to create the 90 bend where it would be welded to that wall colored in green. I would first have the sheet metal cut to size on sheers. Then put a lap bend in the end where it would be eventually welded to the wheel well. Then put a 90 degree bend on the other side, that matches up with the green side wall. Once that is done, use a shrinker stretcher on it to match the radius curve of the wall opening and outside wheel well, then weld into place. I would not mind even trading labor for a sheet metal shop, if thay allow me to use of of the gear like shrinker stretcher. I love working.
I have all summer to do this, but only intent to do this in short order. Its not raining
