hi im trying to install a zzp performance stage 3 kit on my cobalt and im looking for a puller/installer tool kit to remove and install the smaller pulley if anybody has one I would like to borrow it if possible I don't want to buy one because im only gonna use it once if someone could help me that would be awesome thanks in advance

 

Find someone with a press. Stick the stock pulley inbetween 2 pieces of metal, and press down on the supercharger snout. Then to put on zzp's modular hub just heat it up with a propane torch and it will slide right on.
