My proportioning valve is also located in the 73 stock location under the radiator. Since my master cylinder is a 73 & cast iron I ended up making a cover plate from some 1/4" aluminum plate we had at the shop and added a 1/4" ball valve and a pressure gauge, I used some small chain to wrap around the master & plate. I ended up having to use around 15 PSI air pressure over the brake fluid filled master to finally push the brake fluid through master & all 4 wheel cylinders. That finally got them to bleed correctly and I had pedal pressure. I was later told that 7 or 8 LBS of air pressure should have done it but it took a good 15 LBS on my home made contraption to get them to bleed. If you have a friend that has access to a real brake pressure bleeder - see if you can borrow it and give that a try. I'll see if I can find some pictures of my home made pressure bleeder contraption but I did all this probably about 7 or 8 years ago.

That is pretty crafty. On my research through the web, came across a reverse bleeder, also a good idea. Ill see what i can come up with. I know im going to be messing with these old trucks the rest of my life.
