oh many many people I've had to cut about an inch off the input shaft, and they end up using the same pilot pushing in some cases but most of time for guys like you with an undrilled crankshaft, you just get the Mopar pilot bearing that sits where the torque converter snout goes. Take measurements before cutting the input shaft. Put a straight edge across the bell and measure the amount of protrusion, then measure the cranks protrusion from the bell flange at the crank flange. Make sure the input is .080 away from the cavity in the crankshaft.
