I searched all over this site for this info. Im sure it's been said before but I can't seem to find it. I own a 1990 777DY and I'm thinking of getting a reissue edge tremolo for it. Ibanez told me the radius of the reissue is 400MM / 16inch or 15.75. I just wanted to know if that's the same radius as the original tremolo that I have on there or if I'll need to possibly add shims. Thanks.
