Difference between the X - table end plates, is the right side bearing floats axially on the lead screw, the left side plate - bearing can be adjusted for axial play (thrust) of the lead screw to the table.
Crazy project? M8, restoring a bridgeport is as normal as you can get in the world of machine resto... Also, that bearing retainer got its backside blown out by excess amounts of torque the prior owner applied to those capscrews... Tho, i cant call them an idiot, i just had a moment of moronism myself when i was shifting machines yesterday evening... Put a bend into a handle by lifting the machine too close to another machine... My excuse is - I was dead tired, it was the 16th hour of working since 6am, so i had a moment where my thinking wasnt at 100% and shit happened... Luckily no real damage was induced thereby... Oh, and its a jig grinder/edm orbital sinker... That`s why i was moving machines again... So if you think that a bridgeport is crazy, wait until you snag a moore no.2 or some majestic monad of that kind... And hey, a moore no.2 would technically be related to your bridgeport, as moore is to bridgeport what brabus is to mercedes...
I would check the mosfets, diodes and cap on the board. Resistors usually don't fail so easily.
I would get rid of the concrete blocks under the bridgeport shop looks nice though
Right hand side bearing floats. Only one bearing. Keeps the screw from bending due to thermal expansion.
Well, if it's any consolation, Vevor does have unit available at a pretty reasonable price
Just curious, why didn't you rotate the bearing retainer by 30-45 degrees, redrill for the screws and reuse the original part?

Holding long chips is the easy way to loose fingers!! avoid it..if it stuck will cut fingers in half... :(
