I presume that was so the longer "nose" of the transaxle (where Ruf stuck the extra 1st gear) would still sit at the proper location to attach to the shift linkage.
Full disclosure: I have a Ruf 5-speed in my car, installed by the PO, and I'm always trying to learn more about it. I never noticed the short bell housing before today, thus my inquiry. |
In 1978 Porsche went to that rubber center fat clutch disk to cut down on vibration/chatter, to make room for this fat clutch disk Porsche made the bell housing larger and moved the engine back, nothing to do with the wheel base.
Ruf took advantage of that space to make a 5-speed out of a 4-speed transmission just like Porsche did with the 901 box, same dogleg pattern.
The clutch cable is longer on the Ruf 5-speed than the 930 clutch cable since the transmission is moved back.
