Alternative for Jammin X2 center dogbones?

[simplechamp]

I am upgrading my Jammin X1 with a Jammin X2 carbon-fiber chassis from Moos Racing. This means I will also have to get new center dogbones due to the difference in center diff placement.

The thing is the Jammin X2 alloy center dogbones are ~$40 for the pair, and I was hoping I could find a cheaper alternative (also more durable, I'd rather have steel than the stock X2 alloy ones). The sizes are 92mm and 118mm. Can anyone throw me a bone (pun intended) on what dogbones I might be able to substitute?

Thanks in advance for any help!
