Here are two sets of the fittings from disk/drum Toronados. I know that the one on the left came from a '69, and I believe the one on the right came from a '69 too. Evidently there were some engineering changes. Looking at them from the top:

1.  The item on the top is the metering valve that goes between the master cylinder front brake reservoir and the front of the distribution block. You can tell it is mounted in the front brake system because it has the smaller diameter brake line. Both versions have a bracket which bolts to the power brake booster on one of the master cylinder studs.  The one on the right is shown upside down. The metering  valve serves to slightly delay the brake pressure to the front so that the rear ones begin to apply first. Both styles have a terminal for a sensor wire to warn if the valve fails to operate correctly.

2. The item in the middle is the proportioning valve that goes in-line to the rear brakes. It is preferable to use an after-market version since these aren't adjustable, but if you use these be sure to connect it in the correct direction. The cylindrical version on the left has "IN" stamped on the left end, which should be the line from the distribution block. The version on the right should be vertically installed as shown, with the plug toward the ground, the line from the front coming to the high fitting on the right, and the line out to the rear from the left fitting.

3.  The distribution block for both sets appears to be the same. Looking at the picture, the big line to the left goes out to the rear brake proportioning valve. The big line to the left of the terminal on top is the rear line from the master cylinder, and the one to the right of the terminal is the front line from the master cylinder. The fittings on the bottom and right sides are for the two front brake lines. The terminal is a pressure failure warning switch. To understand how it works, visualize a horizontal piston inside the distribution block in a chamber connecting the front and rear of the block. The lead to the terminal is positive (hot).  If pressure at either end fails, pressure from the good side of the system moves the piston and it completes a circuit to ground, thus lighting the brake warning light.
