Folks -
I found some old PM Iron, but it's 3 phase.... Where can I get a replacement single phase 3 hp motor for it? Any leads would help, and I'd rather replace the motor than go a phase converter route.
Thanks in advance!

I did the swap as you're proposing and used a 145tc frame tefc 230v 3hp. That's a C face motor that is a direct bolt up replacement at around $260. They do a 5hp too.
The problem comes with shaft sizes. Depending upon the age of your machine it's probable that you have the three belt system with a 7/8th Arbor and a 3/4 motor shaft. I couldn't find any single phase C face with a 3/4 shaft listed anywhere, even at powermatic. My answer was to switch to the same belt arangement new 66's use which is the 3VX. Confusingly this is a two belt drive and uses 7/8 shafts on both arbor and pully, all readily available. Cost was an additional $180 or so but that was for pully's, belts and new arbor bearings at the same time.
