Does anyone know if the lightened kyosho st-rr spur gear will work with the mugen center diff cup?

I highly doubt it. Different size diff cases I believe. Also, Mugen center spur has the same diameter no matter what tooth it is while Kyosho spurs are larger the more teeth they have and you have to shim the center diff mounts up depending on the spur used.
