I have an odd request. My b4.1 is all decked out in red anodizing. The new big bore shocks coming out have blue on them, that I don't want. I think the big bore shocks you have that have the red spring adjuster rings and the red shock cartridge holder are the same size. Before I order these expensive parts from tresrey I was hoping to get one of each in plastic to make sure they fit. Ifyou have an extra if like to purchase Fromm you. Thanks
