Hi everyone, I know there is a lot written on Mud on this topic and I have read most of it. I have a '73 with a 3 speed and I am swapping it to a 4 speed but keeping the 3 speed TC. I have a 4 speed bell housing. I am trying to decide what to do about the clutch. Am I correct that I can keep the original clutch set up, as I am going to rebuild the clutch while I have everything apart? Since I am investing $$ in the clutch, would you guys switch to the 4 speed set up or stick with the 3 speed. I have a 4 speed fork and bearing hub in addition to the 3 speed stuff. Also, what is on the tip of my speed input shaft - should that be removed?
