1965 Valiant brake woes

Well, the distribution block seems to be lost in the mail. While I'm waiting for it, can I get some clarification on swapping the prop valve for a distribution block?



I contacted Inline Tube and they told me to use part # BLK243. This factory-style distribution block is for 1965-66 Mopar A-, B-, and C-bodies converted to a dual-reservoir master cylinder with disc or drum brakes. Includes frame mounting bracket.
The prop valve has one IN for front and one OUT for front. There must be a tee or splitter underneath the car somewhere, but I can't see it without the car being on a lift. It has the same for the rear; one IN and one OUT, going to the rear of the car.
A friend with a '65 Barracuda swears I need a 5 hole distribution block.
Can anyone confirm whether this is what I need or not?
