'65 c-10 disc brake booster

['70GMCStep]

I'm getting ready to put 6 lug disc brakes on the front (at least) on my c-10. I am a bit clueless on the master cylinder/booster/power brake thing. I pretty much understand the disc brakes that I need, but need some advice with the other part of the system.

What do you all recommend here to use with a 6 lug disc brake system, that may or may not be front and rear. By the way, do you all put on rear with the front, or will I be ok with just front?

I appreciate the advice I have gotten from you all, as I am learning as I go here.

Thanks,
