Still looks like a 66 to me. I'm going by the way the front fender angles back & the body line stamped into the front fender below the headlight area. 64 & 65 were straight instead of angled & then curved below the headlight. 66 had the body line stamped to match up to the larger front bumper. I can't see the tail light well enough to be sure about it. The 66 front end could have been bolted onto a 65 car.
I think I read something in one of my books about a Valiant rally car before they went to the Barracuda body. Can't remember the year though. I'll have to do some digging.
