I know that a generator shovel right case can be matched to an alternator shovel left case, I was wondering if the same could be done to a knuckle right case and an alternator shovel left case. I realize that this would result in a bike with no numbers, but in Pennsylvania you could title such a bike as reconstructed and they issue a "blue tag" which has to be "permanently attached"to the bike. I have '70 and 78 shovel left cases as well as the flywheel assembly to the '78. A friend has a knuckle right case. Could any of this be put together? Could later 80 inch shovel flywheels be used? What pinion shaft would I use? Can any one help? Thanks for your time.
