Ultra mbx comp question
 

I recently got an mbx comp. it was missing the center diff. I was wondering if the hyper 7 tq diff would work becouse there are different spur gears for it and not the stock mbx center diff.

I think The Hyper uses different size diffs than the Ultra line. I know I had 2 Ultra's a while back, and then had a few Hypers and none of the Ultra parts fit the Hyper especially the diffs, and vica-versa
