I am in possession of the original owner's manual for a 1968 Shelby 8T03S 115975. Also lists #76B-Y-6A-07M-8025108-5 and was issued to Elaine Holbrook in Cavendish, VT. on 6/20/68. Book is same for GT350 or GT500 so don't know which the car is. It was sold through Stinson Ford Sales inc. I thought maybe the car might still be out there and the current owner might like to have this manual. Please contact me if you are interested at dswallshirley@aol.com.
