Thanks Malcom. I have found a couple of places that seem to have consumables. However, the critical part I need is a plastic base or foundation which mounts in a rectangular hole in the vertical divider between the transformer side and the wire spool side of the machine. On one side is mounted the wire feed motor and on the other is mounted the feed tension roller. The internal end of the MIG gun liner is pinch mounted to the base as well. I am afraid this would be a factory order part. I will see if I can get a picture to post.
