I installed an overdrive in a 66 cuda about 25 years ago and the clutch pedal was not hard to push like this set up ended up being. I have since removed the od in the cuda. i took a look at the bell housing i have from the cuda and the fork. i put it onto the engine i am working on and installed the tranny. The fork that was initially in the car that hung low wants to spring down to the bottom of the bell house with the tranny installed. The fork that i had in the cuda wants to spring upwards becoming more centered in the bell housing opening. This may be the reason why the one i was using wants to sit lower in the bell housing. I need to find another z bar and see if it all lines up now.
