Non-ABS Master Cylinder Ports

[rtbwmu]

Anyone here able to tell me which port on the non-abs master cylinder feeds the front brakes and which the rear? I know normally you could just follow the lines, but the rig I'm working on, the lines go into a proportioning valve that isn't stamped with F/R on any of it's ports. Thanks!

the forward is front. it routes to the T under the mc, then to each wheel

Awesome thanks. That’s what I thought but then I read in another thread for 80 series that they were reverses in those trucks and I got concerned.
