I put these on a vintage Ludwig floor tom that came with those awful old spring-loaded leg mount brackets and they're great. I recomend getting these with the key-screws so that you can fit the drum into standard cases as the wingnuts stick it out quite far.
I think you are thinking of the BR3 (and yes, the BR3 can go in place of both Ludwig lug hole spacings). The BR2 goes in place of brackets (not in place of lugs).
Do you sell a bag of key screws and nuts if I want to eliminate the wing nuts? If not can you recommend the nut thread size and key screw manufacturer? gibraltar etc.
