I swapped a 4.7 out of an 02 Durango into a 02 ram 1500. Changed the reluctor ring and all the timing stuff. Now I'm ready to put the clutch on the motor and install. But the pilot bearing that it calls for from autozone does not fit. It is to big on the OD. Did the cranks change on that spot between the automatic and Manual Trans? Do I need a special Pilot Bearing? Do I have to drill the hole bigger to use the bearing I was given?
