I recently acquired a 1976 C-10 longbed truck with the 250 6 cyl motor and the three speed on the tree standard gearbox.Due to lots of floor rot ( ok this truck has a serious case of lepracy) the engine pipe on the exhaust has split, and i will be putting in new floorboards. Once i do this, i will need to replace the exhaust system. Ive been to two different auto parts houses, and neither of them have a listing for the exhaust system for this truck.This truck does not have a catalyctic converter on it , and the only listings in the Walker book are for a 1977-1979 6 cylinder without catalyctic converter. Will the same system from a 77-79 truck fit on my truck?
