Dist rotor support?

[KaDrifter]

I'm putting MSD on my 240 right now and i'm following the instructions from the jim wolf website right now I can't get the chopper screw loose (rotor support) only God knows why the put a philips head in there instead of a bolt(right underneath the rotor in the center of the dist) Is there any way to get it out easy? could i put a impact screw driver on it(i'm guessing no)thanks

they are in tight. if you have the type of screw driver where the handle is hard plastic and squared off it is likely around a 7/8" wrench size. Make sure you get a good bite inside the screw so it doesnt spin and tear up the screw. Use a wrench on your screw driver while pushing down on it to break it loose.
