LF spacers/response pads

so i know they sell them in the store. but im looking for some new yyf spacers that will fit protostars/northstars. maybe 2 sets if someone has a spare. also some yyf response pads that will fit in a protostar. i have 3 center trac bearings i dont use, so i was looking to see if anyone wanted them but didnt want their spacers/pads. let me know if anyone has some!

would also trade a bearing for maybe 2 counterweights. id like a duncan ball and maybe a dice or something idk. offer something maybe ill find it interesting!

I got a Ball CW (yellow) and 2 yellow pads if interested
