If I can see thru the haze in my mind I believe B/W auto trans used a small pilot. Not much bigger than a bushing in a normal crank. That is for the sixes in the late 60's. Now the Buick/AMC/early Rambler/ Jeep engines had a larger hole and a bushing for the turbo 400. The question is what did they do with the 304? When did it get stuffed into Jeeps? I still agree with Andrew, I have never seen a RWD car that did not have a pilot hole of some sort. I have seen Front/WD cars that do not use a pilot, but their bellhousing is extremely short and IIRC their input is long enough to have one bearing at the spot the input exits the bell and one farther back inside. sort of the pilot is in the trans thinking.
