Time for brakes -- Bought a booster bracket last fall from Captainfab, found a brake booster from a 75 Impala and bought a rebuilt master cylinder for a 75 Impala. Modified a proportioning valve bracket from a S-10 to mount a 70's GM combination valve, then spent two afternoons bending all new brake lines. I ran 1/4" to the rear drums and 3/16" to each front disc. Should stop better than the original set-up.
Double flares are sure hard for me to do, I messed up several times. I hope they all hold when I bleed the system.
