3600,
Look on any mid '70s (give or take) Chevy "C" series. The only difference between the pedal assemblies for the 6cyls and V8s is the length of the cable! It is a hanging style pedal that comes out with just two screws for the whole assembly! Get the carb bracket too, even id just to use as a pattern or modify. What I did was to measure the height of the pedal bottom in the stock location so I would know how high to mount the pivot on my firewall. It is so easy it'll amaze you. Get the newest one you can. The pivot block is some kind of plastic and does wear.
best wishes,
Les
