I have a '73 that I put a 460 in, currently has a C-6. Thinking seriously about converting to clutch and manual trans. So.......do the smallblock 4-speed cars have different linkage parts than a 429 4-speed car ? I'm just guessing that the pedal assemblies would be the same, but maybe not the linkage. The thought occurred me, I need to know this before I go looking for parts. Thanks a million for any insight !
