Our bridgeport clone knee mill ballscrew yoke finally cracked, and now I need a new one very badly. Does anyone have a spare?

I have bought parts for Amura and Accra machines from the following company in the past. It has been awhile since I have had contact with them. Maybe they might be able to help you out.
