For a Turbo Clutch Bellhousing, Your Standard VW Clutch Release Cross Shaft is Needed on a Exchange Basis:
A standard VW clutch cross shaft from a bus transaxle is needed in exchange with the turbo bellhousing kits, as they are modified on an exchange basis. There ate lots of different VW clutch cross shafts, but the ones needed were used from 1975 --> 1992, and are 215 mm long, and 20 mm diameter, as shown below (part number 091 141 701).
The early bus (1968 - 1975), 16mm diameter by 215mm long shafts (parts number 002 141 701 or 002 141 701F) are NOT sutiable, and neither are the mm long, 20mm diameter by mm 200mm long shafts fitted to Beetles (113 141 701F).
Note that the shaft shown in the picture has had a flat ground onto if between the release forks, for use with a naturally aspirated, ‘push to release’ Subaru clutch
