When requesting info or offering info regarding pilot bearings and pilot tools, it helps to clarify which gearbox we're talking about, because the Dash 1 and Dash 2 input shafts have differing dimensions.
ZF Model .... Pilot Bearing ... Input Shaft
------------------------------------------------
5DS-25/1 ... 15mm ............ 1-1/8”/10 spline
------------------------------------------------
5DS-25/2 ... 17mm ............ 1-1/16”/10 spline
The clutches require different friction plates too, for the same reason (input shaft size). The transition to the “dash 2” transaxle took place in February 1972, approximately chassis 2600. The Dash 1 is attached to the bell housing with 4 symmetrically placed studs, whereas the Dash 2 is attached to the bell housing with 5 studs. Since the gearboxes are oriented upside-down in the Pantera, this difference can be easily seen, making them easy to distinguish from each other.
