Rear brake line to P. Valve.

[CRUZE 418]

Guys, my '69 Dart was pretty much hacked together when I got it. I am replacing the brake lines etc. Look at my pictures. The lines are from Inline Tube. There are two lines in the rear kit, what goes in between the short line and the long rear line? It's not just a regular splice, the two end fittings are different sizes. Their website shows a possible Rr hold valve? The valve looks just like the bottom of my new P valve.

If you have oem front disk the upper distribution block is only a distribution block then down where the two lines are not connected there would be a proportioning valve.

dist block 67 -70

1967-70 Mopar B-body Distribution Block, Disc or Drum


Proportioning valve

the combo valve as you have is from a later year or other model car or both
