Hopefully, you set number one piston at Top Dead Center (TDC) and made marks on the distributor in relation to its location on the engine, or at least remember the direction in which the rotor was pointing. If you didn't, then the first thing to do is set TDC and then stab the distributor. At TDC, the rotor points to the number one spark plug wire post, follow the firing order from there. While stabbing, you may have to rotate the distributor left or right a little to get the splines to mesh.

There is a different procedure for every car so you need to get a repair manual. Generally you would line up the rotor with a mark on the inside of the distributor and then line both those marks up with one on the intake manifold where the distributor is inserted, all this is done with the engine at TDC.
