I think the "dent" is indicative of a mid year production 1971 and up inner fender. Tav, is your car a 70 or a 71? One of my M46 cars is an A/C car, I can take some pics of the passenger fender, it is untouched original, other than most of the A/C stuff has been removed! There is no water valve or any hoses in the area in question. Hmm, I also have a shell from an early production 71 Challenger with 70 original inner fender still in place. I can take pics of that one, it is easier to get to. Tav, do you know what an original 70 only E Body water valve looks like? I have been looking for one for years, and I probably wouldn't know what it looked like if I saw it unless it was NOS in the box! Looking forward to meeting you at Carlisle Colin!
