Blower is a DSC-1. Once I switched over to manual steering and brakes, it was a bolt in. I did have to modify the crank pulley ( cut of the outer belt groove - think it was for an A/C unit )so it would clear my fan shroud. Running a 4" blower pulley and around 12-15 lbs boost. The 3.7" pulley will up it to around 25psi boost.
