The clutch pedal arm has new rubber bumper on it. It sets the gap on the arm to the floorboard, I assume to the right gap, I'll check. I adjusted the clutch free play to give my throw out bearing the proper clearance. The brake arm activates the original OEM brake light switch. I put a rubber bumper on the brake arm to not over travel the switch and smash it against the floorboard. If I did not, the switch lever would be the only thing stopping the brake arm, and it would be even higher. There is a little difference between the two arms, one is angled, and one is straight. The pedal shafts are 2.5" different in length. My master is the original rebuilt, my clutch is the original 10 3/4" pressure plate but a new disc and throw out bearing.
