I have a vented optispark rotor and cap. The cap is good condition and rotor has a little wear but I think its still usable.
New is $130 at Autozone..I would take $50

I also have an LT1 water pump for sale. It's only been on for a very short time (since Jan or Feb I think).. Make an offer.

Reason for selling: I'm selling the opti because I was getting a bad stumble from my car. I thought it was the opti spark but it wasnt.. Come to find out I had a fried wire. I'm selling the water pump because I changed it suspecting it was bad because I was getting a weird hiss. Problem was I didnt get all of the old gasket off when I installed it back on. Being stupid, I went ahead and bought a new one.. again..

As for trade, I'm looking for a set of over the valve cover wires with looms that would work with long tube headers.. Let me know what you have...

PS: Buyer pays shipping and I take paypal or COD..
