I HAVE DEALT WITH THIS SAME ISSUE ON MY JAP JAGHH.
The japanese jag had a gotoh bridge which had some buzzing issues, so i replaced the bridge. i got a nashville from stewmac (or a similar site). THIS DID NOT FIT. It was meant for small bushings, which are not what you are looking for. You are looking for a large bushing bridge. translation - this:
w/screw holes and not this:

btw - i made the nashville tom work by grinding down the screws to fit the bridge. now has a tighter fit than traditional bridges, longer saddle throw, and only buzzes on the low e (i use .59 E's).
may want to consider a roller tom if you use the vibrato liberally.
