Not sure what you mean by flat threads, but the threads had a flat look to them. Nt sure if they are ACME threads or not? Regardless if they are bad, by all means replace it.

Your arbor should have acme threads, which are flat. The only reason to replace it is if it is worn down enough that the saw blade gets too much runout from not centering well.
Get a dial indicator and check the arbor for runout and axial play. Replace if necessary.

Congratulations!
I have a 1956 Unisaw that runs like a champ. Mine was missing the original motor cover as well when I bought it last year. Instead came with an ABS plastic replacement cover that works just fine. You will definitely want to put the Bies fence on the saw. It's a much better fence than the jet lock.
