Fender 5 mounting holes bridge vs 3 mounting holes bridge

Hi,

Do you know if Fender's Deluxe and new HMV bridges (3 mounting holes + sting thru) are using the 3 middle holes from a standard 5 mounting holes bridge?

In other word can we drop in the new style bridge, use the 3 middle holes on a body that use fender's standard 5 mounting holes, and drill for sting thru?

thanks for your help.
