Looking for ideas on brakes/boosters/masters

[bbcmudtruck]

I want to shave my firewall this winter and I'm looking for ideas on what you guys did with the big old bulky brake booster and master cylinder. I have a 73+ complete brake system. The prop valve is located down on the front cross member, just like it would be on the square body trucks. What I would like to see are ideas and solutions to having a cleaner firewall. IE smaller boosters, relocated boosters/masters etc. I would also like to get some ideas on how to plumb the brakes in order to keep as much is hidden as possible. Thanks!
