Been looking at NAPA, Autozone, Summit... does anyone make a replacment proportioning valve that will fit the 1966 Riviera??? The ends of the brake lines were so nasty they're broken off and froze in the original that mounts to the frame just below the master cyclinder. I just did all new lines, master cylinder, pads... I REALLY don't want to alter the car and want it as original as possible.
It's not a prop valve ,just a junction block,inline tube or the brake companies should help you find one .
