Changing Jackson tremelo on Models 2 & 3

[MSGfan]

Hey Guys!,
I'm wanting to change the Jackson trems on my late `80's model 2 and 3 to either an Original Floyd Rose or a Schaller Floyd Rose.
Which one is a better drop in replacement for the Charvels that came with the Jackson trems?
Anyone know which one works best with the exsiting trem posts and trem route?

Thanks for any info.!

Either one will drop right in, no mods needed.
