Welcome to the Stovebolt!
My 1965 had S10 seats. I was lucky to find a stock seat at the salvage yard. I first bought a 1967-1972 seat and it bolted right in. I later bought a 1966 seat so it would be "correct". The 1967-72 seats are a little different. It didn't fold forward. I think you should look for a 1963-66 seat if you want it to fold forward.
