I think I'd just get some bar-stock from scrap or Enco drill it to match the toothbar, grind to fit on either end, and get some longer grade-8 bolts to bolt it on. If you have the ability to weld, I'd put a couple of strong tack welds to attach it to the toothbar. As everyone suggests, it should function without problems.
When you're through, we expect to see it and pics of the project in the customization forum.
