Wilton #654 Vise - Need a spindle nut

[goodysgotacuda]

I have a Wilton #654 4" vise that could use some TLC. It has a couple of threads broken off within the spindle nut. I can't seem to find any online sources for this part, any suggestions?

Thanks!

Further research shows that it might have been superseded to #675? The #654 looks extremely similar.
