Austin,

You're going to have to tell us where you are getting confused.

The Marelli distributor points should be set to 0.016 in for a 1971.

The timing is set by rotating the distributor - you loosen the clamp and it will turn. As it turns the timing changes. My dial timing light looks like the one at the bottom of page 71. I find ground and power in the engine compartment at the 3 fuses under the cover on the left of the engine compartment. The sensor is clamped around the plug wire going to cylinder #1 - left rear. Start the car and the light will flash. Point it at the crankshaft pulley and you will see the timing marks move as you rev the engine. It helps to see the timing marks if they have some white chalk in the timing groves. Now set your timing light dial to 35 degrees, and rev the engine until the crankshaft pulley marks quit moving. They should stop with Z1 pointed straight up, aligned with the mark at the bottom of the alternator housing - as shown on the bottom of page 72. Rotate the distributor until the marks line up with the timing light dial set at 35. This may take a couple of tries as you might want to just rev the engine quickly, get the reading, and then let it idle while you rotate the distributor and try again.

Let us know where you are getting lost.
