I picked up an unfinished 66 El Camino rebuild where he started to add power brakes and an IROC rear end/axle. All connections have to be made.
Question:
The dual reservoir master cylinder with the front compartment larger than the rear (each with an outlet) has to be connected to the P_valve. The P_Valve has two fittings on top, two on the bottom and one fitting at the upper rear that is about 45 degrees off vertical. Is there way to determine what connects where? The rear axle combines the rear wheels into one line at a hose connection.

Any hints?? Do the connections matter??

In a 'regular' disk/drum or disk/disk setup, the front and rear connections go something like this: The prop valve has a port on either side of the electrical brake light connection. these are the 'in' ports from the MC. The prop valve should then have two 'smaller', possibly angled ports on one end and a larger, single port on the other end. The larger, single port is for the rear lines and the two front lines connect to the two smaller ports on the other end.

Hope that helps,

Thanks for both of the responses. Putting them together with the pics I received, I shouldn't have a problem.....

Im doing the whole disc brake swap on my Chevelle right now also....at the same problem...have the P-Valve figured out, but...I know where the front left and right lines go, but which is which? Top right? Bottom left? Or visa versa? Thanks-

B66, from the info that I got; the front 45 degree fitting goes to the drivers-side front and the other (bottom) goes to the pass-frnt. These should be the same fitting size and the smallest fittings on the P_Valve..
