-I personally wouldnt watse my time on a balster coil unless the original one died, but its only 30 bucks so its not a total waste if you want to go ahead and get it.
-AC Delco plugs are fine, dont bother with the bosch +4's or whatever else is out.
-the wires like justin said
-I never noticed anything special about the MSD cap and rotor, except they are red, I just used your standard parts store replacement.
-If your feeling really saucy, then go get the MSD billet distributor. And toss in a 6AL box while your at it ..
