I have an 04 cobra with a wipple supercharger, my crankshaft extension support pulley is bad, it wobbles at an idle and straightens right up if i pull the throttle back even slightly, it seems to be common with terminaters, it is def not a bent crank and not the harmonic balancer, the balancer spins perfectly straight behind it... My biggest problem is Ford no longer makes the part and i cannot find one any where... Where can i find a replacement pulley that is the stock size, i do not want to add any additional boost considering my whipple supercharger is already pushing about 22 lbs as is.
