The safest would be a universal clamp with a mini boom arm mounted directly on the tom holder. P.s. i am jealous of that kit, i am looking for that very rig.

Here is a idea using an adapter sleeve- use a rod (instead of the tom arm) to mount the cowbell.

Here is another example of the Rogers cymbal arm adapter used for a cowbell

Thanks for the input! I love these drums, first set after owning all Slingerlands. The sound is phenomenal. They look sweet and the Cortex is bullet proof! The Memri-Loc, though not aesthetically pleasing (some don't like it, i think it looks fine) are built like a tank. They don't move. The Slingerland hardware looks pretty, but doesn't hold (or is as versatile) as the Memri-Loc. The set is 24/13/14/18. Snare is a COB 6.5x14 Slingerland. These were real dirty and had a few small interior cracks on a drum or two, but everything else was great. I believe mostly all original too...

Thanks for the information! I really appreciate it! I this still available? Or is it something i'll have to look for on the used market, eBay, CL etc..?

Thanks again! Sweet kit too!

The adapters come up on eBay fairly often. Check the FB pages for Rogers Group 2 as well.

Thank you sir!! Will do

Here is the mount you are looking for. Add a round rod to clamp the cowbell on.
