I checked the SuperCharger pulley, which we don't change out, and it appears to also be the same type 8 rib as the tensioner so it appears that will be what is used for the 6 rib belt. I'll confirm with ADM, but @ this point, it looks like using the kits pullies are it!
SC Pulley:
Next the air bleed (steam line) and then test fitment of the SC!
