Can someone with a TCI roll stop tell me which port is the master cylinder side. The port closest to the coil? Both ports are stamped "master" and both are "XXXXXXX" out on mine. Tried calling TCI 2 times and waited on hold to long.

Also does it have to go after the proportioning valve or can it go between the master cyl and proportioning valve.

While I'm at it, is the proportioning valve different on power brake cars and manual brake cars with disc brakes.

74 duster with front disc brakes. Thanks.

Thanks hemifred, that clears up the proportioning valve. Problem is when you get to step 4 and it says its stamped master and brake. Both of my ports are stampeded master and they are both x'd over.
