I think the one with less length to the splines came from a Task Force series trucks. I don't see any problem with using it.

Either will work.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.

My understanding is that clutch gears with shorter splines are OEM and the ones with the full splines were aftermarket. In which case the aftermarket parts would be presumably stronger. I don't have any evidence to support this claim however.
