you might just wanna go with a new cap and rotor they are only 120 bucks from summit. depends on how bad the opti is or what your finances can take

I would replace the cap and rotor just like Falcon said. Summit has the MSD-84811 for 154.88. I'm running this in my car and works great. Be sure to buy the water pump gaskets as you will have to remove to replace the cap and rotor. Might not be a bad idea to replace pump while you have it off, if you haven't already.JMO

If you decide to buy an Optispark I have a Brand New GM ACDelco one for sale I'm asking $265 shipped but open to offers. Link is in my signature.
