Some time ago there was a guy here from Texas who wanted to Clone the Lisk Challenger and was looking for information. That's probably him. If it is then I set him up to call John and he never did. I never saw him back on Moparts either so I think he may have just joined to ask about the car and never came back.
EDIT: I looked back at my notes and it is not the same person so 71Challenger may in fact have owned the car.
