Update- I just had a nice 2 hour+ conversation with the owner and as it turns out he lives in the same town as me here in Massachusetts and he knows one of my relatives. Between this thread and other forums, I was able to get quite a bit of info on the 66 and some on the 68, including ownership history, so he knew that I did some homework.
He purchased these 2 cars as an investment (66GT350 in 2000 and did not recall when he got the 68) and apparently has a number of other cars. He has no plans to sell them at this point, however, that was not out of the question, but did ask for my contact information, keep in touch and grab a coffee.
If anything comes out of this I will let you know. Just a sin to seeing it get all musty and mildew as it is starting to get.
Again, thanks for all of the feedback and who knows what may come of this. Took me 5 years to find my Boss2, and it may take 5 to own a Shelby.
