Ooops, forgot you question. I think the VIN might be JH, the VIN being most telling then contact Barry Washington at the Hamtramnck (Spelling?) Historical to see if he has record of this car.
Obvious things to look for are fiberglass T/A hood, passenger rear mounted antenna, no antenna hole in the passenger front fender, I think the front fenders were special in they had notches on the top arch of the fender lip. Rear spoiler. Look under the trunk lid for 4-5 rectangular holes cut out of the understructure for access to bolting down the T/A spoiler. Not all 1970 Challenger trunklids came with them so if you see just small round holes to access the nuts for the T/A spoiler then either the trunk lid was replaced or the T/A rear spoiler was added to a regular Challenger. T/A cars could come with either standard or Rallye gauges. If Rallye Gauges then the tach should go to 8,000 rpm, not 7krpm unlesss it was replaced. Reset knobs should go through the wood grain on the dash and not the lenses for the 1970-1971 style rallye set up.
I think, but not positive that there were column shfted T/A cars, again, not positive on that...
Could be other stuff, others will chime in...
