Well you could try cen direct, is basically the same thing as the SH28, [link=http://www.cenracingdirect.com]CEN store.[/link] just click the link and you'll find what you need. The HPI stuff won't work on it, maybe Kyosho or Ofna. Or if you can find any other type of Pullsart in your LHS that fits. I would take out that one way bearing carry it to the LHS and find something on the shelves that fits it.
