Port valve from master cly.
 

I have a OEM port valve. I had a after market port valve on my truck when I took it apart 11 months ago. With drums brakes all around. My question is: How do I figure the brake lines out?
I have front disk brakes and drums on the rear. 1/2 ton 2 wheel drive 1972 front sup. and 1972 rear end. so the brakes are 1972 set up.
below is a picture of my master cly. and valve. both came off a 72 with disk on front and drums on rear.

1/2 ton 3/4 ton? year model?

And more importantly!
Discs/drums or just drums.
And it's called a proportioning valve if you have disc/drums and a distribution block if you have drums all around.
