Mine was worse than that but not from rust. Poor quarters, an old collision fix, and some wheel well rot. AKA hack job over 50 years....
Where did you get all your metal? I bought all AMD products. quarters, door shells, fenders, inner fenders, i/o wheel tubs, one piece floor, one piece trunk floor, firewall, all cowl panels up front, a piller on drivers door, back panel, deck filler, bumper filler, cowl hood, trunk drops, x-brace support, radiator support, window channel, trunk channel, dash top, firewall both sections, outer rockers. I think I was left with the shell, roof skin, and deck lid! All others had either rust, damage, patches, etc....
Hope its worth it cause its costing a fortune!
