68-76 4 speed pedals compatibility?

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

Don't know about aftermarket. You might check out Brewers for parts/info - Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists
