wherever that saying about 2 piece shaft being for alignment is false..
We'll all learn something as Riki puts miles on this re-design.
Studebaker in 1951 and Packard in 1955, design engineers working independently, both came up with a wobble joint in the distributor/oil pump drive shaft.
Studebaker V8s have the joint at the bottom of the distributor. Packard put theirs at the top of the oil pump.
There are two pieces with mating joint to machine, a pin to install, a sleeve to install, another pin to install and peen. Seems like a lot of trouble for something Riki feels could be one piece.
His theory the wobble joint isn't needed is partially supported by most later V8s,
i.e. Ford, Oldsmobile,
etc., used an unjointed intermediate hex shaft.
The big block Mopar is the only V8 which comes to mind mounting the driven gear on the intermediate shaft and a bushing in the block.
If I ever get the urge, I've saved a BBM drive shaft. It would be interesting to convert a Mopar electronic distributor to fit the Packard and drive it with the BBM shaft and bushing, down to the Oldsmobile pump.
