I have my stock blower off my 07. It had 62k miles on it when removed and still has the stock pulley on it. It never had any other blower pulley on it. Spins freely, no weird sounds or anything. Was only removed for a Posi ported blower. I also have the stock plenum elbow and the stock throttle body as well. I'm asking $450 for everything plus s&h. I'm located in Leesville, La 71446. You can pm me your cell # if you are interested and I'll send you pics of everything.
