Vantage avenger guitar tremolo

Hi there,
I ve bought this Vantage avenger guitar made by Matsumoku which I found in a very good shape. I want to replace the tremolo bridge for a back one. I'd like to buy it from Guitar Fetish but since I've never replaced one I ignore which are the measurements I need to consider before requesting one from a store.  
Does any body have idea of what kind of tremolo this guitar has on?

Strat style floating tremolo.
Measure what you have and find the same.

Yeah... easy peasy!!

Important numbers are the distances between strings at the saddles!
