I'd like to move away from the CAS setup on my Cosmo for use with my E6X, what specific items will I need to run a REW from cover/pully setup on my Cosmo with PS ?? I realize I need the pulley set and a front cover for an REW ?? is the spacing for the belts and such going to work with the alt,wp and PS ? or will i need to use the REW alt and so on

thanks
