WTT: 30mm buttons/modded SE stick for 24mm buttons/hitbox

i have 6-8 seimitsu 30mm colored transparent buttons
and i think 4 spare 30mm sanwa buttons
a modded SE madcatz stick with sanwa buttons, sanwa JLF stick, ball top and bat top

i’m looking to trade all of these for a Hitbox stick, or parts for 11 24mm buttons
