Will a YZ engine fit with YFZ swingarm?

[guy310]

Does anyone know if a YZ450 engine is the same width at the swingarm pivot as a YFZ engine?

I'm fairly certain that the yfz is a different width, and the pivot bolt is a different diam, because i looked at trying a yfz swingarm on my yz hybrid, not even close.
