Crack open a bleeder on the rear and you should be able to push the plunger.

I tried compressed air pushing back through the front port of the distribution block (I am using this term interchangeably with the proportioning valve - on my car I have a cast iron distribution block that is mounted on the frame under the master cylinder - unlike the 69-70's that have a brass one attached to the master cylinder) with no luck. I assume the plunger is pushed forward since there is fluid to the rears - so pushing air from the front should move it to the rear to allow fluid flow to the front? Interesting thing is that the compressed air comes back through the master cylinder but yet no flow the other way.............??? Are you saying to crack a rear bleeder to relieve some of the air pressure in hopes the plunger moves?

Appreciate all the comments and suggestions.
