The truggy CVD's wouldn't. However the buggy CVD's will. HB diffs are interchangable with kyosho diffs. Since all competition legal buggies are limited to the same F/R track width the it follows that most should have interchangable front and rear CVD's. Difference between differential width assemblies would change that, but since the Kyosho and HB diffs can be swapped, the cvd's should be as well.

My LSP used LST shafts and sportwerks boots to make the cvd's while using kyosho 7.5 based aluminum hubs. Worked fine.
