C5 or C6 brakes on a 70 nova?

[LowchevyII]

I have a 70 nova and im looking for some new brakes. In trying to keep with the pro touring theme i was looking for either c5 or c6 brakes. I want to go 4 wheel disks being the current set up is disk/drum.

I think i am going to use the ATS front spindles. From there i was wondering if anyone knew of any good kits either c5 or c6 that would work and what modifications would have to be done on both the front and the rear. Also, currently i am using a gm 8.5 10 bolt rear. I would really like to find how to incorporate the c6 stuff on it but any info c5 or c6 would be much appreciated.
