I put an axle from a 1977 on my 1970 Fj40 for the disk brakes. I just got the proportioning valve from SOR but Im not sure where its supposed to be mounted. I have the body off the frame right now on mine and cant see a logical location for it to go. If someone has a picture of a 76 or later proportioning valve mounted up please post it. If no pic but you know where its supposed to mount that will help too. Thanks
