Big Brake upgrade... which booster/mc/prop valve is needed?

[biohazardbill]

So da burban will soon be moving under its own power. That being said I need to be able to stop it. I bought McGaughys 13" setup for the front and rear a while back so I will be using that.

What booster/master cylinder/ proportioning valve setup would be appropriate for such big brakes and being both disc front and rear?

How hard is it to mount the booster directly to the firewall instead of using an adapter bracket?

Thanks in advance.
