Just to finish this post off, wanted to confirm I replaced with the new T-57-R switch and everything seems to be working normal. it was essentially a direct transfer over without having to change anything except the AUX connection previously mentioned. All wires reached their connection slot without having to redo them either.

Figured out what the original Generator AUX connection does. Without it I could not turn both A/C units on at the same time, only one at a time. I just moved it into the Generator Neutral connection with the original Neutral wire that goes there too and can turn both on at the same time now. This makes further sense as also just realized the original switch had a permanent jumper in place between the Generator AUX and Neutral (Control Panel section had the same). It is easy to put both wires in the same connection block as these are smaller diameter wire so both fit easily.
