Zillaguy Posted September 7, 2013 Report Share Posted September 7, 2013 About to buy a new set of CPI in-frames from a friend of mine, he is not sure if they are SB or BB... Is there a way to identify them by looking at them? They are brand new w/silencers, never installed $600.00 Just bought his new never installed chrome Durablue +4 axle for $100.00!
