Thanks that would be great. I think I could just buy a couple aluminum cases for ~$12 if you have the gears and bearings at least.

Would those work?
Seems like the ring and pinion are the most expensive part if I were trying to build the diffs out of parts. Any alternatives that would fit in the losi case?
