78 Camaro big rear disc conversion??

[Aceshigh]

Guys, looking to do a rear disc brake upgrade to my 78 Camaro.
I have 17" rims on front and rear.
Already have a C5 brake conversion done to the front.
10 bolt rear end, looking to upgrade that in the future to a 12 so
need something that will be flexible for that later on.

Looking to upgrade my rears to big disc as well, (w/E-brake) and dump the ugly
booster and master in there now for a hydraboost setup.
Looking for thoughts and options for what systems I can purchase.
So far I have 1 suggestion from Nastyz28 for this kit.

I don't want a set of cheap non-zinc coated rotors, that's my only concern.
A member of Nastyz28 named Ed Miller is working on a C5 rear setup with E-brake.
I'm just not sure it will be done on time for my consideration.

Any thoughts or fingers in the right direction would be appreciated.
I've been considering this Hydraboost system....not sure though.
Looking for feedback on this as well. http://www.abspowerbrake.com/camaro/6769camaro.html
