RC8 centert diff/Kyosho plastic spur/bearing size?

[The Cow]

Hello my friends,

I know you guys will have the answer

I had purchased some of the Kyosho plastic spurs some time ago. I am just getting to installing one and I notice the bearing much to wide... I am assuming I need to change the bearing size and som shims to protect the plastic spur from the pin?

Any input on what you guys are using in high powered BL apllications is appreciated!
