x2. I take the distributor cap off and rotate the motor until the rotor is at 12 o’clock to the motor. I mark the distributor body right at the lip where the rotor is pointing with a paint marker. Pull the distributor, with a black magic marker, scribe a line at the top of the clamp all the way around the distributor body shaft. The reason you want to do this is that it is entirely possible to get the distributor installed and the motor running, without the distributor tang engaging the oil pump slot. So the black line helps you confirm the distributor is in at the same depth as it was when you took it out.
install the new advance On the distributor, leave it loose, install the distributor, install the hold down bolt and center the octane selector to 0. body and rotor pointed to 12 o’clock, tighten the clamp screw. You have this!
