In case anyone has LS-30's and wants a round restrictor gate instead of the stock square one, I can confirm that one from the LS-32 WILL work. I just got mine from Lizard Lick yesterday. I haven't used the stick yet, but the parts physically look identical (except for a set of extra nubbies that may require dremeling). I can't comment on performance yet, but, when I do, I'll post my opinion.
