Parts Express and Mouser are both reputable dealers. Be sure to get a PC board, the pot is made for board mounting, not for direct soldering. There are man posts about it, see for example

Thanks Ken-

The value for A1 and A4 are supposed to be 445 ohms each- So I had my multimeter set to 4000- I(t goes 400,4000,40000) So anyways, the A1 terminal is right on 445 ohms, but I wasn't getting a reading on A4. I took your advise and cranked it up to 40000k and now it is reading 25.03-

It was getting late when I soldered this, and I've already found a couple joints that weren't soldered that should have been. Thanks for the tip on the meeting though- I knew it was something simple, but just couldn't put my finger on it. Still very much a soldering noob-  Hopefully I can find what the issue is tonight-

You had said before that both sides light up...

On the side with the OA at 349V, can you report both Kreg voltages on that side?

0L is actually over limit. If you don’t have an auto ranging meter you need to increase the range to one greater than the resistance you are measuring. To test your meter just measure a known value resistor out of the circuit and see if you get the correct value. Just be aware the value you read might not be exactly right because of part tolerances. But it should be very close.

Chassis panel is 8"x12" so base is a bit shy of 9.5" x 13.5". About 6" tall.

Just a follow up to this, I was able to find a pot for sale from Mouser:

It looks like all the specs check out, but just as a sanity check, does this look correct?
