Proportioning valve question for disc brake conversion

The photos are showing the stock setup, the proportioning valve is integrated into the distro block / brake warning light block.

Earlier years 67 till that went with single piston 72-73??? Was set up that the MC lines went to the distro / brake warning light block. The the rear line went out to the proportioning valve then to the rear end.

IMHO you would want the proportioning valve after the distro block IF it has a brake warning light in it. Other wise you will be feeding one side of the brake warning system with higher pressure then the other and the light will come on at every brake.
You are talking about 67- 69 cars. the 70 -73 a body cars use this valve and it has the pressure failure light switch in the valve you can see where the wire plugs onto it in this picture.

Here is a link for the correct valve it is also used on the a-bodies. I have a bunch of these valves and I took them all from 70-73 a-bodies
