What size response are mod spacers compatible with? It looks like 12mm pads… but I can’y tell for sure and can’t find it anywhere.

The mod spacers I have take duncan silicon stickers. I haven’t seen any that take response pads. I saw an add a while back for mod spacers with a C-bearing. Dose anybody know where to get those.
