I have a proporting valve saved from a 74 Newport I'm using on my 65 New Yorker which I put front discs on. After cleaning up the outside of the valve I opened it up and man, am I glad I did. There was enough goo in there to start a goo factory. Anyways I cleaned everything up real good with brake cleaner and put it all back together with brake fluid. Does anyone carry a kit to replace the o-rings and stuff on one of these?
