Metal Vice - can this be replaced?

[DogwoodTales]

So I acquired this this metal vice and the nut (I don't know what else it may be called) is cracked into thirds.
Is it something that can be replaced?
Where would I get it from?
Thanks

Looks like the harborfreight vice. Had one just like it and it broke the nut too as well as generally sloppy. Check harborfreight for a current model and see if there is a parts breakdown in their instructions then see if they van get it.

Thanks - that's a good start.
