but yeah I rarely ever get rid of good original parts.. esp for these type busses.. if nothing else there are good useable parts that someone can use even if i cant

Love those old GM/Delco parts used throughout the GM product lines. All were meant to be opened up and repaired/adjusted in the field. Even the relays and other special purpose widgets they designed for the vehicles were able to be opened and repaired. All that info and details are in the GM coach manuals. Very detailed and adjustment specs for most everything. Meant to be repaired.
Funny story from my misspent past. One year at the annual Grad Night (multiple nights over about a 10 day period really) Parties at Dizzyland, one of our companies 4104's wouldn't crank and start. It was pretty obvious that the starter solenoid mounted on the starter wasn't engaging the battery leads to provide full current to the starter. You could actually kick it with your foot to engage the starter solenoid in case the low current side wasn't energizing the coil. There was a convenient part of the clutch lever exposed so a foot could help things along. Very nice touch. But even this wouldn't crank the engine.
Anyway, it wasn't passing the high current so I opened the solenoid cover and removed the large copper disk that was the contractor itself between the high current contacts. I cleaned it up, got rid of crap and corruption obviously insulating it from passing current across the contacts, brightened it up and put it back in place and reassembled the housing. Gave it a start and it worked like new.
All this while waiting for our passengers to come out at about 0500hr or so. It's an all night vigil with, at the time, many hundreds of buses from all over the State coming in on multiple nights from different High Schools for Grad Night at Dizzyland.
Back in the days when the drivers had a clue, and the buses were easy, and meant to be worked on. Those were the days, the buses, and Grad Nights, are pretty much all gone now. The world has changed.
But I've got my Crowns and will eventually get me a coach, or two, so I can keep them alive and in good running condition for all to see how things were in the simpler, non-computerized days of 'yore.
By all means you should mix and match to gain a working starter ready to go against the day of need. You'll thank yourself later.
