68-76 4 speed pedals compatibility?

Anything to corroborate that? I've never heard of the pedals having a different ratio.

Pretty sure the z-bar has different ratios between a v8 and a slant, and I think the fork is a different length. Or maybe the z-bar ratio is the same, but they don't interchange due to tube length and only the fork is different. Not sure.

Either way, never heard of the pedals being different beyond the bushings and spring brace.
Yea I’m hoping the pedals other then the HP ones 340 would all be the same. Hoping it’s 3 different z bars or clutch rods.
Any idea how the aftermarket is for these parts or terrible fitment. On Oldsmobiles they send you Chevy repops and they barely fit a Chevy let alone Oldsmobile but our pedals were different year to year not via pivot pin or engine size
