Thanks for the information. My brother and I bought a 1970 AMX (20421 dash plaque, brown, leather & AC & PS & disc brakes, 360 Auto.) in 1975, and sold it to DiSalvo AMC in St. Louis (I think the owner gave it to one of his children) in 1978 to buy a '79 Trans-Am with the Pontiac 400 and a 4-speed. The AMX was a better car, but we needed more seats.
I hope that DCX uses one of the old AMC names on one of their new models, especially if it is a nice looking one.
