If you have a 948 OR 1098 cc engine the existing engine pulley will work. If you have a 1275cc engine, your harmonic balancer will need a V cut into it to drive the supercharger. This is an easy modification and can be done by me if you send me the pulley or any local machine shop.

I will ship internationally.
