What Center Diff works w/ plastic spurs?

[jhautz]

What ceter diff works with the plastic kyosho spur gears that are sold in the rcmonster store? http://www.rc-monster.com/proddetail...YOIF148&cat=40

I have a center diff from the hyper8 and when I put the platic spur on it it binds up and wont turn.:mad: If I back the screws out a turn or so then it works. I have all of the shims out so I cant make it any looser. It is really close to working, but not quite. Any sugestions?

Anyone know of a center diff that for sure works with the plastic Kyosho spurs?
