ok i bought a basket case blaster..i know the frame is a 2004,but it has the drum brakes not hydro.is this possible?the fronts are ok for now but i am looking to convert the rear to hydro.what is needed to do this?the pre 03 brakes are on it now which leads me to believe the rear bearing carrier is pre 03 also..how do i find out?i know it has the triangle brake mount.would i need a post 03 carrier to mount hydro?can i change just the bearing carrier?sorry for so many questions..very comfused:-/
