i went through the same thing with my 82. in the end i bought a welder and did patch panels for the rusted areas. the bed panels were easier (imo) to learn on than the cab. they are easier to line up, cut out, and weld in. you have to start somewhere, might as well be there! if you do get a welder, spend a fair ammount of time on scrap peices of metal that are the same thickness as the patch panels and practice welding peices together, the more you practice the better you get!
