My YZ-10(T) '94!

[micholix]

Could anyone please clarify to me, from wich yokomo car this zc-632G is?
I had a look at some yokomo tc cars manuals, but could not find this part, neather in the hop up listing...
It's actually a main gear adapter, but with one way bearings in it!?

There were two of them comming with all the other parts, one new in pack, with hardware and bushings and one new, but packed in a kitchen bag without any other parts.
