SX3 to KF diff

[westyguesty]

I thought I could use an sx3 ball diff with kf pully and fences in my kf. I had an almost new diff that I thought would be good to use in the kf.

Just tried to swap to the new pully and the hole in the middle is bigger than the sx3 pully. Has anyone tried this and come across the same problem.

Thanks.
