About 1982 or so, we got hold of a 61 Bel Air 2 dr post car without engine and trans. It was real oxidized from sitting outside for a long time, but all the trim was there, and no dents or rust. A good cleanup job helped its appearance a lot. We stuck a drive train out of another race car into it and ran it at the '83 Winternationals. Didn't do particularly well with it, but we had fun. My buddy also had a roller '61 Impala sport coupe. We surmised that it would be neat if it were possible to swap the trim, emblems, and the dash parts between the two cars to make a 61 impala 2 door sedan, and a 61 Bel Air hardtop out of the two. We noticed the doors on both 2 doors were the exact same length, 48 1/4", as were the doors on the 63 Impala sport coupe and the Bel Air 2 door post I had that I raced. That would have provided all the necessary side trim for both cars, the emblems, the dash parts, the interior widgets applicable to both models, and a lot of other things as well. It never happened, however, and that was probably best, who knows what we would have gotten into that we didn't know about. It's the unseen enemy that gets you rather than the one in your sights.
