UPDATE:
I spoke with the last known PO today. He said they sold the Bronco about 5-6 years ago. The new owner lives in North Alabama! But, there is some good news, and some bad news. The good news is, the new owner restored the Bronco and put new uncut quarters in it. The bad news is, the guy I spoke to told me he bets $25k wouldn't take it. So it looks like this one may never be back in our corral.
That doesn't mean I'm not going to at least try. ;D
I've got a name of the current owner (hopefully), and I'm going to try to get into contact with him. I will try to at least go see it and take some pictures. Of course, I'm going to ask him to sell it as well, and tell him if he ever decides to, I want to be the first to know!
