Now the not so pretty...
The floors need fairly minor patches, which is easy enough at least (i'd look for actual 70-74 Challenger metal to weld in there, none ov that new crap). And as for the interior... well, it was a desert car, and what the desert gives back in metal, it certainly takes away in everything else. Seat cushions are toast, dash pad is toast, drivers-side interior panels are toast. Headliner was beautiful... and still bright red, nary a scratch... until it just fell down one day. Dammit! Everything else survived though.
