I went and looked at a perfect rust free 641/2 D code Mustang body today minus motor. It was a 1 owner car with a clear title and it had the owners manual in the glove box with the vin# info on it. It also had the correct warranty plate on the door to match the vin# on the title. Now for the weird part, the car had been wrecked in the front end back in 1970. They took a complete front end clip from a 66 and put it on the 641/2. So the vin number under the hood thats on the fender panel is for the 66. Don't know the history of that vin#. My question is if I bought the car should I send the orignal title for the 64 1/2 in and get it transfered into my name or get a bill of sale for the car with the 66 vin#. If anything ever happened which would be the legal vin# to go by. I thought I could change the panel under the hood that has the vin# on it and do away with that number but isn't there some more locations on the front clip that has the vin# on it. Thanks for any suggestions on this matter.
