Let's take a close look at the pitting and wear of the pulley surfaces:
Here's something that I only learned after the job was all done and cleaned up ... someone seems to have made the mistake of replacing only one pulley. Maybe they thought it only had one idler pulley when they went to the parts store, or maybe that pulley went bad?
In playing around with them, I was
at my spending the time and money - the older looking of the two has a bearing that is catchy / crunchy to turn! It was going bad and I didn't even know it!
OK, here is one other picture I edited since somewhere in my multi-forum search I came across someone asking about if they had to use a spacer, or what order they went in, or some such question. I can understand how a guy (or gal) might drop the parts when pulling them out, or pull the bolt first and having everything drop. I was lucky and paid attention to the order it all came out. Despite having new spacers that came with my 'Chian' pulleys, the old spacers covered the front of the bearings better, and seemed to fit just a hair tighter into the inner-sleeve of the bearing - so I re-used all the parts from the old pulley's bolt attachment.

Chuck, thank you so much for this tidbit of info. It really helped cut the confusion.
My decision was to take off the negative battery terminal, then unbolt the alternator to get it out of the way. I didn't fully detach the alternator - I left all the wires connected - but this gave me ample room to see the nut you told me I'd have to address, and room enough to move a ratchet on that nut (which turned out to be somewhat easier than relying on the ratchet that was on the bolt head).
