My first car was actually a Sprint cpe. w/ 4bbl.,so I`m somewhat familiar with the engine, just never knew of any convertibles with the OHC-4BBL. So, does anyone know or have any advise on where I can find out how many of these were actually produced? I know the # of Sprints produced in `68, and I know the # of ragtops produced in `68, but I don`t know how many ragtops were Sprints?
