How much clutch travel do you have before it starts to get harder to push down?
If more than one inch I adjust it so the pedal has minimum travel (less than one ich travel up scope wrench) before it starts pushing on the pressure plate, I buy the A body A motor clutch rods to use in all my 4 speed cars, the stock B and E bodies are a lot shorter than the A body rods are scope up
