I’ve converted my 67 with new rear disc conversion from drums from Right Stuff. I’ve also installed new stainless lines, Wilwood MC with 1” bore, New 8” Dual Diaphram Booster and Wilwood Adjustable Proportioning Valve. Problem is that I can get good flow from rear calipers. Even bought a Motive Power Bleeder and was able to get some fluid out of rear but not enough to engage calipers. Fluid coming out like crazy at rear banjo bolts while depressing brake. Been at this for a month now and need help?? Thinking maybe didn’t adjust E- Brake properly???
