Shaft seal question

You are taking about the piece of the seal that is conical in shape and was being held in place with the small pin that the impeller locks on to,right? If so, and it is the metal one, they can really be a PIA to remove without doing damage to the lower carbon seal that is inserted into the top of the motor housing.
Maybe a picture?
You may want to try some PB Blaster on it but in such a way as to not get it on the lower part and chancing ruining the rubber inside the seal. I feel for you as this was usually a no go situation and we usually replaced the motor and installed a new ceramic style upper seal.
Again, the part number for a new seal is 00-077107. Does your machine have the gravity drain on it? If so, you can see if you can locate a new motor p/n 00-070380-00001. It does not allow the drain pump to be attached and only works with the gravity drain.
Maybe someone here on the forum can help you with the parts as they were obsoleted by Hobart back in the early 90's and these are the commercial versions. The domestic versions techniclly became NLA in the mid to late 70's.

I'm a little jealous...

Especially when I see that CAST IRON spray arm. What a contrast to my MOL 2014 Whirlpool with a tinny "stainless" arm and the "fishtank" pump. That KitchenAid will probably still be running after my WP quits (I give it five more years, I'm not too confident that the fish tank pump will hold up).

You can definitely see Hobart DNA in that wash arm. It's like a scaled-down model of the ones in the conveyor and the single-tank machines. I remember being invited into the kitchen of my grade school by the lunch ladies. I was intrigued at all the different appliances back there: Blodgett ovens, a pair of Koch and McCall fridges and freezers, Vulcan ranges and the Groen kettle. The one that intrigued me the most was the Hobart single tank machine. I got a peek at the inside and saw the massive spray arm. To a third grader, it was a little ominous looking.

If I could make a recommendation, I'd see if a metal fabricator could fab a trim piece to go around the window to give it a more streamlined look.
