You can reuse the /4 PP and clutch disk, but you will need to change the flywheel . You need the early flywheel from the 2.0 /6 engine, that flywheel will bolt right onto your crankshaft, no problem.
Alternatively, you can keep the 2.2 /6 flywheel and convert to a pull type clutch, which is slightly bigger, 225 mm vs 215 mm, IIRC.
The latter solution is slightly more involved: in addition to a new PP, throwout bearing and clutch disk, you need to modify the transmission housing and use a shorter clutch cable. There's a couple of threads on this.
How can you ID a 2.0 / 6 flywheel? I am converting to a six with an original 914/6 case, 2.2 P&C and 2.2 heads. I got two flywheels with a bunch of parts a guys sold me for the conversion. Just want to be sure what I have will work.
