Dude, there are several threads about this already on Jemsite. You should do a little more research before you start the 10th thread about this guitar.
But to answer your question, I must first point out the fact that there is no "
Edge Pro III." The bridge on the RG350DX is an 'Edge III' which is based off the original Edge trem. And with it being based off that trem, it apparently has the same dimensions because it is directly swappable with an Original
Floyd Rose.
