Magnum crank and 4 speed

for the cranks that aren't drilled, you cut one inch from the input shaft of the transmission and then use the needle bearing Mopar performance pilot bearing that presses into the torque converter register. The input shaft seats in the bearing and the register but still seats in a regular pilot bearing... because non drilled have a slight drill depth to them from the piloting when they machined the register...just not the full depth of a drilled version. Many folks did this including myself
