this must mean that the diff outdrives are also a running change. did anyone else notice this change? it means I have a bunch of parts that are no good for B4.1 now.
that's the optional ball diff for the sc10. the ball diff outdrives fit the tranny case for the gear diff, which is stock for the rtr/kit sc10.
