I recommend making a pair to fit your mill. Make the body out of HRS and insert-able jaws from tool steel. Air hard is fairly easy to harden at home and a lot of home shop machinists have a small surface grinder. BTW, one only needs to indicate in the fixed jaw, just like with any other vise. If you don't have a surface grinder I have one for sale.
