71 duster slant 6

all 4 drum breaks have a runner line going to one as well as rubber line in center of the rear axle that I didn’t see before.

We kinda figured that and were being smartasses....

Hard lines along rear axle to slave cylinders, rubber line to hard line under body to pro valve, hand line from pro valve to frame rails to rubber line to front slaves. 99% of all cars made run this way. Calipers instead of slaves, bun non the less same or similar...
