1964Cuda, Thanks for the feedback. I'm unclear as to what combination valve you have there, it may be just the dual circuit distribution block with the switch in it; as was used for '67 to late '69, '70. My research tells me those do not contain a proportioning valve, and the proportioning valve was a separate piece after the distribution block before it went to the rear axle for those years (see my link in post #12 above to the Mega Parts '67-'70 proportioning valve that I have ordered). Inline tube has a video showing the changes from '62 into the '70s.
Hi Bob,
Yes I believe the one I got is for like a newer style aftermarket, may not be period Mopar correct, that is a combination valve with proportion and front hold off or metering all in one.this is what was sold to me with the master cylinder and all the lines bent to fit. Along with rebuilt calipers, LCA and new rotors.
