70 disc brake hold off valve?
Anyone have experience with 70 disc brake hold off valves? I don't believe that you can buy the guts for them?
I have an NOS hold off valve for a 70 big car. I am wondering if the insides would have the same seals as the A body? I am assuming that the springs would be differant for the heavier car. What I would like to do is rebuild my original using the old springs and the new seals from the NOS one.
Is there a place that would tell how much pressure it should take to push past the hold off valve? I didn't see it in the CSM.
