Steve: Lloyd used to have this on his site but since removed it. I found it from a GT40 brother. This is all I could find. It says the input shaft has optional sizes. From my research, there are 3:
1. Original M1 ZF: 29mm
2. Pantera -2 ZF: 1 and 1/16"
3. Supposedly a third ZF: 1 and 1/8"
All 10 spline. All I know is the one I need is 2. which Performance Gears calls the DeTomaso input dimensions. Wilkinson thought the Pantera was 1 and 1/8". I have confirmed that is wrong and 1 and 1/16"
