You're not going to find one for less than 80K. Most of them are in then hand of people that know what they have. My suggestion would be to buy a 67 fastback junker and use "Yearone" and other places to build it back. Make it a Shelby Clone. I had a 66 GT350 back in the early 2000's and it was 35K for a needs restoring car.. Best of luck to ya.
