No need to pull the distributor, but you will have much more room having the distributor,wires, out of the way.
Put your motor at tdc (top dead center).
With the cap off, the rotor should be facing the no.1 cylinder.
Unbolt the distributor hold down, and pull out distributor.
Simple stuff.
yeah, you don't HAVE to pull the distributor - but it sure is easier having it out of the way - and even if you happen to put in back in 180 degrees off, you'll know it right away
