The 901 is the same spline as all aircooled VW's, a beetle disc will fit...not that you would use one.

The picture I posted above is an adaptor I made out of a VW flywheel, a CSP performance VW bus 228mm pressure plate and a Sachs 228mm disc. It all bolts to 3.0/6 engine and a 901 (914) transmission.
Note that it would fit any 911 flat 220mm flywheel.
The later 240mm flywheel won't fit a 901 case

BTW When I built the transmission I changed the gearing to A, F, O, X, HA (flipped).
