are you talking about the service brakes or emergency/park brakes? if service brakes,do you want the whole thing from frame mounted booster, residual valves, proportioning valve, through to brake hoses and how the lines were run along the frame? are you thinking vac booster, hydro booster, stock linkage and single master cylinder or stock linkage and tandem master cylinder (non power brakes is what I mean by stock linkage, single versus tandem is the master cylinder, stock would be single system so all the brakes run off one circuit. those went out in the 60's due to safety reasons but some still run them to be stock), stock trans cross member or something different (if going with power booster it may make a difference if you run a manual gear box and a different cross member). firewall mounted booster would also make a difference as far as residual valves etc.

just a bit more info required as to what your plans are that's all.
stock master cylinder or tandem (upgraded for safety but can still use stock drum brakes if that's what you want)
power brakes or non power brakes
frame mounted or firewall mounted booster or master cylinder set up
drum brakes all around, like stock, or upgraded disc front drum rear or disc disc
stock front axle or ifs (ifs style and donor car or ifs manufacturer would help)
stock engine and trans or something different

that will give us a start

pics, of course, would be good. yes, we could go through your build thread and other posts but that is time consuming on our end. you know we all live for pics of somebody else's rig. we get ideas and also can spot things you have maybe missed that will give grief later on.
