I have a Get 1 Screw with the Roush supercharger and recently a couple pulleys need replaced. I found one but can't find a replacement idler pulley. Reached out to Roush and yes they seem to have deleted that pulley and created that FEAD Shield Kit but I'm showing it requires the SC to be removed. I'd rather not do that for a pulley if I can just replace that pulley. Has anyone found a replacement idler pulley thats the same size as the Roush one? The Roush Part #116219a216aa.
