You will need a timing light or vacuum gauge. You will have to loosen the hold down bolt at base of dist where it stabs into manifold. When the timing light is correctly attached at the #1 cylinder, front one on pass side, you will see a pulse of light when squeeze the light trigger and shine down to pointer at harmonic balancer. Look up the spec and verify that any needed vacuum lines are unplugged and capped as per spec. Rotate the dist to correct point, tighten down hold down bolt and reattach all lines/wires. You can also attach vacuum gauge and see if max vacuum is achieved when at spec. With cap off you can move the front of crank slightly forward or back and see how many degrees slop is in chain before the rotor starts to move.
