is there a difference in calipers between a 2006 SS/NA and a 2006 SS/SC, is it possible the caliper from the SS/SC be larger than the SS/NA...

let me explain my situation, i am 90% complete of doing a full conversion, from front disc & rear drums to 4 wheel disc, the rear is complete, brakes suspension and all

my probleme is the front end, new back plates along with new rotor, the rotor very well fills the back plate space, but once the caliper installed, the pads dont sit well on the rotor only ¾ of the pad rest on the rotor ¼ of it sits outside the rotor

i am starting to think the supplyer sent me the wrong calipers, hence my question is there a difference in the 2 type of calipers
