Doesn't have to. As long as the rotor points at the terminal on the cap that is connected to the #1 plug wire (at TDC of course), it will work just fine.
Find TDC on the vibration damper. Make sure that it's TDC and not 180° off. Or remove #1 spark plug and cover the hole with your finger. Crank then engine over with a remote starter and when you feel pressure building up, that is your compression stroke. Get the #1 piston to TDC.
Now look at the distributor and see where the rotor is pointing. Make that terminal on your distributor cap for #1 spark plug wire. Now follow the direction of distributor rotation around the other terminals on the distributor cap 1-8-4-3-6-5-7-2.
