Posted April 11, 20223 yr comment_639230 While this forum post is an excellent read, it still doesnt help me get any closer to actually rebuilding the stock NP valve. Any suggestions where one would find new O-rings, Y-seals, lip seals, and cup seals?

Heres a photo of the NP valve on a 78. Big difference from the one on the 240z's Link to comment https://www.classiczcars.com/forums/topic/67401-1978-280z-brake-proportion-valve-seals/#findComment-639238 Share on other sites More sharing options...
