STD cases: need help

Description: I realized that the flyweel was a 1957 type and not match to the right case bearing of the case

Hello guys,
I need help to solve my problem.
I was rebuilding a (I believed) 1962 Panhead.
I purchased a S.T.D. set cases for that year tipe motor
During assembly I realized that the flyweel was a 1957 type and not match to the right case bearing of the case i purchased. Sad
How can I solve my problem? ???
Can I upgrade my flyweel replacing the pinion shaft whith the '58 type (O.E.M. 24006-5Cool?
Is there a right case bearing that matches the pinion shaft of my flyweel (1957 type)?
Thanks a lot

You can pick yourself up a '58 pinion shaft and install it on the right flywheel. Give the assembly a good, up-close inspection. Particularily, the bearing surfaces on the crankpin and rod races.
