Yes, you can retain the 260-8555 1" bore Wilwood MC. We typically spec a 260-8556 1 1/8" version for a slightly firmer pedal, though your existing 1" version will run appropriately. Frank can set you up with either system # 3021 or # 3023. The new design Wilwood MC is a GM early / deep MC pushrod interface as you pull it out of its box, and this can plug n play with our # 3023 assist unit with the long MC rod. Or? Alternately, these new design Wilwood MC's come with an aluminum spacer plug or bullet that inserts into the deep MC pushrod hole for use on the 2nd Gen Camaro / later short MC rod spec - will interace with our # 3021 model when run with the spacer bullet.
