I went with an electronic ignition to git rid of problems with burned points and bad condensers.

I am not a fan of the one piece shaft . This assumes the cylinder head is a true concentric fit on the block witch may not be so . The head studs are not a tight fit in the head . With the two piece shaft the coupling sleeve acts as a slight U/J . I make sure the connection is a slip fit not a bang on job . I think with the one piece shaft you can get bushing wear in the distributer and points gap slop over time , just watched Paul Shinns video , just my thoughts .

Even Paul indicate he prefers the short shaft distributor. Iy is his customer that wanted the long shaft.

I’m a good mechanic but what you wrote just reinforces all that my dad used to tell me and that was “ A good mechanics will do a crap job when he thinks he knows everything, it’s just a matter of time on a certain vehicle”.
I never gave the short shaft vs long shaft a thought till I read what you wrote.

A spring loaded distributor drive and a spring loaded plunger controlling camshaft endplay, and a spring retained oil pump all allow for deviations in load on the sprung function. The two piece distributor drive shaft helps isolate the distributor shaft from shock and side load from this movement.

Almost every ‘western auto’ single shaft I’ve seen is bent
