I'm trying to help a friend install a Wilwood master cylinder and proportioning valve in his '67. The truck has front discs from a '71 with the 5 lug swapped drums in the rear. We are attempting to attach the original 1/4" rear line to the rear port on the proportioning valve. I'm hoping someone has already done this and can help locating an adapter fitting. What I need is a 3/8"-18 male inverted flare to 7/16" female inverted flare. Any help would be greatly appreciated.






This fitting supplied with the M/C has the correct female side but the wrong male side, not inverted flare.
