With that in mind, it would seem worth the effort to pull the distributor and fill the open bore with your favorite thin rust-buster and leave it overnite to steep. Bonus Luck points if the liquid makes it thru to the drive rotor.

$.02 from the cheap seats.

That'll just dilute the engine oil with rustbuster, won't go anywhere near the oil pump! 

The pump drive shaft bore is not connected to the circulation pathways. Those ports are in the case. If you remove the base plate, the sump will not drain; the oil must first be drawn up by the action of the pump.

their shared spindle which is driven by a gear on the crank shaft. 

Hammer time.  Supposed to start at 11:00 minutes.

Based on what the rest of your car looks like I would whack the crap out of it until it falls off.  Most likely the pump has never been removed and was submerged under the ocean or wherever your car was sitting to get so rusty. No offense about your car I just mean it’s literally probably just sealed on there from the years and years of neglect and outside environmental forces

A 45 year old jap car without rust? All z's i have seen are rusty. Only only i have seen that was rust free sold for over $100k

It depends a lot on where you live. My current project was very rust free. And only required two small floor board patches. They are getting more rare though

I dont see that gear and shaft for the dist driver on the exploded views of the engine. Pics would be appreciated

The video shows the shaft and pump assembly.

this is the gear on the crank that that spindle engages with, as it goes diagonally across the top of it at about 10 o clock.
