I've got all new rotors, calipers, pads, bearings, hoses, lines, master cylinder, and booster for my 73's brake system. I actually still have to order the brake line kits. I'm just going stock replacement. I was not able to find a prop. valve replacement except I think those adjustable ones advertised sometimes in Mopar Muscle. I degreased my original one and then sprayed through each opening with brake clean. Everything flowed out the opposite ends well and I saw no rust colored fluid come out when I shot the brake clean through. I was planning on just spraying it black and reusing it. Do I need to do anything to it or get it checked out further anywhere? Mine came with power disc brakes up front and has the 11 x 2.5 drums in the rear when whoever swapped to an 8.75 rear end.

My Father-In-Law and I were talking about this a couple of weeks ago.  He says there is a method to testing them but we didn't get into details.

I'll ask him this weekend about it and if no one else chimes in, I'll let you know.

I just used the wire wheel on mine for a bit.

I'll keep my eyes opened about how to test the dist block / prop valve

Unless you have a test bench, the only way to test a prop valve is on the car with comparison gauges hooked up. The FSM outlines the procedure.
Pardon me but my karma just ran over your dogma.

I took one apart before that was in an engine fire. It's been a while, but if I remember right there is really nothing to wear out. The one in the fire looked brand new on the inside. I think the only problem you could have would be corrosion.
If it ain't broke, fix it 'till it is.

That is exactly what my Father-In-Law told me this weekend.
