Woodworkers Emporium, a US company, has Vicmarc parts. Don't know which ones, but a search kicked back over 400 parts for a variety of models.
Maybe try the
Vicmarc website and use
the contact page? They have their email address, phone number (Australia) and Facebook page listed there.
Made in Australia, if a OEM motor/other electrical components are used it will need a converter 50 to 60 HZ and 230 to 110 volts. I have no idea if there's a US model with 110v/60HZ electrical components.
Another possibility would to be to buy another used Vicmarc and use it for parts.
