I'm working on a 1970 challenger and bought a power booster and master cylinder from leed brakes. The challenger has front disc and rear drums. Can't figure out where the lines go. Called leed and they said the master cyl is for a ford because they are more readily available. The portioning valve is mopar the one with 2 parts. Does anybody have a diagram as to where the lines go to? I took pictures of my proportioning valve but my computer won't download them from the i phone.

Wayne, I just redid my power disc/drum brakes on my 70 A66 Challenger. I have the two piece front to rear brake line with a proportioning valve on the frame underneath the drivers seat. First thought; get the proper Mopar brake master cylinder. I put the brake valves together outside the car copying the original valves I removed.(Pic 1)
Important note; early 70 Challengers had the two piece back to front brake lines, about mid-year the proportioning valve was integrated into the valves by the master and a one piece front to rear line was used.
Pic 2 proportioning valve on frame. The diagram shows where the individual lines go.
Let me know if you need additional information

Master cylinder that should fit properly (thermometer front) https://www.carparts.com/details/Do...VaSytBh2FrQ-cEAQYAiABEgKKQ_D_BwE&gclsrc=aw.ds
