Hi Marcus,
I did the SBCC set on the front only, including the dual res master cyl. The lines fit nicely. The factory hd drums on the rear were sufficient for my needs. The caveat here is that you're forced into pretty small discs if you stick with factory 14" wheels, 9" rotors I think. I found a set of 15" rallys from a later model skylark and those fit the 11" rotor. The backspacing is slightly different but no issue with suspension travel or steering.
