My 1972 240Z (10/71) originally came with a 4 speed transmission. Some time later it was converted to a 5 speed. My question concerns the clutch slave cyl. Must you use a different slave cyl for the 4 speed as opposed to the five speed or will the clutch slave cyl be interchangeable between the 4 and 5 speed transmission. I need to change mine (slight leak) and don't know which clutch slave cyl to order!

Thanks to all for your help....

It should interchange.

The really good part about that early 71 is it is adjustable where as the later ones are not. Make sure you usr the clutch fork from your origional 4 speed (it has a hole in it for the adjuster) This will give you the ability to adjust your clutch.
