Antti told me about this thread last weekend at the races and now I just found these two pics from somewhere on this ClassRacer forum. It's Ted Flack's Duster... Could this be the same car?
That AMX is one of the original factory made Super Stock cars. It's #41 and nowadays it's driven by an AMC enthusiast. The car is in really nice condition nowadays and runs 9.7 ETs regularly.
