Great looking project you got going. I can relate to your different problems as I needed to replace the lower quarter extension, outer wheel houses, floor pans, inner front fenders, panel below the rear window, and the panel below the rear tail light that the bumper mounts to on my 71 Challenger RT 2 years after I bought it. When I bought the Challenger it had just had a quarter put on and new trunk floor along with a complete paint job just so someone could turn a fast buck. Keep us posted on your progress.
