Red face New question about proportioning valves

I'm putting a 93 mustang booster and master cylinder in my 54 but the rookie in me is coming out. Can anyone tell me where the 3rd line that come out of the bottom of the mc goes? I've looked on different web sites but it only show that it has a 3rd line but it does'nt show where it goes. Can that line just be plugged?

Sitting here at my store, I am guessing, but I have put Ford truck and van prop.valves on my trucks, and 2 lines go to the front brakes, and one to the rear. Not much help, but may be a step in the right direction.

I guess what I'm looking for must be a master cylinder question, there are three fitting/lines that run from the master. two of the lines go to the proportioning valve and one goes somewhere, that the one i'm looking for. It run from the middle bottom of the cylinder. I don't know where it goes.

Welcome to the forum. My Chrysler MC is as Gman described. Two lines to the front and one to the rear. I would guess that the Mustang cylinder is similar...

Just looking at the pic in the Ford parts catalog,it looks as though that style master has a small proportioning valve that screws into the bottom of the master and the rear brake line may screw into that?
If thats the case then the 2 front lines would go directly to the calipers and not through a valve.
Just a guess.Pic isn't very clear.
