Not sure what they're called but I need (2) of the black spring steel pieces that screw inside the channel of Ludwig clip mounts, to stabilize drums & keep them from wobbling. Searched the Ludwig parts catalog and found the part number for a complete mount assembly but no breakdown or part number for just that piece. I have the mounts except for those pieces; however if someone has the complete mounts with those pieces I'd be willing to consider buying those. Alternatively if anyone has any ideas as to how fabricate a suitable substitute I'm open to suggestions. Thanks in advance.
