The difference is not if its a pushbutton or not but that it has a ZF-1. The ZF 1 has a shorter input shaft than the ZF 2 which is why it requires the crank adapter in the 'goose. Unless there is a ZF 1 with a longer input shaft or the Pantera's bell housing is shorter or some other difference, there will be a difference in the distance from the shaft to the crank in the ZF 1 equipped Pantera as well. Buttondoor related that he had run his without the adapter (which originally came with his car) and destroyed his trans because the crank didn't brace into the crank. I don't know if he experienced warning vibration prior to the damage. Any thoughts?
