I will revise what I posted above.
I have seen a 1953 Power Glide crank that did not have the pilot bushing area bored out to accept a standard size bushing.
All 1954 and later cranks I have seen are bored for a pilot bushing. Chev would have given the 54 crank a different part number just because of the pilot bushing machining change from 53.
The cranks all interchange but in the case you have a 53 crank, and are using a stick transmission, turning down the OD of the bushing to fit the crank is necessary.
