How do you change the rotor bottuns on the 2000 civic?

hi All,
it's time for my 30K maintenance and I was hoping that you could help me with changing the rotor buttons on my 2000 civic?. I believe the rotor button is attached to the distributor via a screw, but I could never get that screw to line up at a place where I can insert a screwdriver to unfasten it. Is there another way I can get to the screw without taking all my plugs out and rotate the crankshaft counterclockwise to get to the screw?. Thanks for your help. Andrea W
