I just bought a used Pearl MLX kit (late 80s/early 90s). The floor tom is missing its legs, so I need to get some replacements. The brackets are obviously designed for a thicker leg than Pearl is using currently. Anyone know the diameter of these legs? 12.7mm (1/2") seems like the only readily available size that MAY fit. Just not sure if these were some other special size unique to Pearl drums of this era. Also, anyone here from Pearl know if there is any back-stock of the floor tom leg memory locks that go with these brackets? Thanks.
