That's weird the second one is my exact car!!! Same spray paint looking thing on the hood and everything! Every detail from the stripes interior, marker lights is the same.
I thought it might be based on the description. You should contact that website and have the ad removed. Sometimes 3rd party vendors like that will pull info off of the internet to boost their traffic, I had to contact one about my Satellite long after I had purchased it.
You aren't listening. You'll never be able to prove it's the only one optioned like that. The records you would need to prove it do not exist. Same for the last '72 340 Demon. There is no definitive proof, because the records no longer exist.
