Quoted from Pin_Guy:
This is literally a part that should never fail, you may have to make one from a SS bar of the appropriate thickness and width. I don't have the specs to provide the exact bar to cut the part from but you will likely find what you need at McMaster-Carr
It appears that the previous owner bent it back and forth a bit...I may have to do the same to get it back into a acceptable shape.. a new one would have been nice though..
edit...found it...Mantis makes it(but listed under a different machine)
