Great progress Dave. The brake distribution valve(s) look like something from the wheel well of the 737 "A" system hydraulics. Hard to believe only one fitting sealed, but I'm not surprised. Also, thanks for confirming that your car bites back. I was looking for cold medicine the other day and found 4 one-half full boxes of band aids. Mostly used from car and home project accidents.
Anyway, your work looks great.
