I have the above combo. I purchased it with things all bolted up but not yet started.
I got the double arm for the porsche 915 tranny but cannot move the throwout shaft at all.
I pulled the tranny and everything looks OK, but I do not know for sure what I am looking at.
I reinstalled the tranny and made sure the arms went to the slot in the throwout bearing. Bolted it up and still cannot move the shaft to release the clutch.
Since I did not put in the clutch, How would I know it was the correct clutch for this combo? Any idea why I cannot rotate the shaft? It seems like it is supposed to pull the throwout back away from the engine toward the tranny but cant do so.
