The Ofna Hyper 8 center diff????

[MetalMan]

I am using two Hyper 7/8 center differentials, each with a Kyosho plastic spur gear on them. The Hyper 7 and Hyper 8 use the same differential parts, maybe besides the spur gear. Both of my diffs fit the gears, but if I remember correctly, I had to remove some of the shims to allow the plastic spur gear to fit properly (without binding).
