Ok i have recently bought i modded lynn fury and i have this old center trac from my broken die-nasty by yoyofact :)ory . I was wondering if i could put the c bearing center trac in the lynn fury by yoyojam . 
YUP! I popped the Center Trac out of my Die and put it in all of my “C” sized Yo’s just for fun, including my Lyn.
go for it.mine fit in my legacy,speedmaker,and atmosphere.it should be fine.one thing you might need to do though is put shims on it.other than that good luck.
