I think all TOM bridges and tailpieces have the same centres. I know the PBG bridges have the same spacing as a Gibson TOM bridge (as I've got an example of both). What they don't all have are the same post/post hole sizes and post insert sizes (and the original Gibson TOM just has a thin threaded post that screwed directly into the wood, with so inserts). As long as you get a bridge that comes complete with posts and inserts that have an 11mm or greater insert diameter (widening the hole is easy, making it smaller is a lot harder), then you should be fine.
