I completed the installation of the rear brake plumbing with the installation of the clutch and brake pedal assembly from Chassis Engineering, and the power booster and adjustable proportioning valve from Hot Rods USA. When I get the front crossmember from Chassis Eng. and install it I will send it and the brake and clutch pedal assembly out for powdercoating.
Note that I made the steel bracket to protect the underside of the proportioning valve and rear brake line. I wasn't comfortable with the thing hanging there unprotected from road debris, dead animals, etc.
