Sweet did you get them from the same guy I did. If you did you need to let him know that you learned about them from me and the forum. I told him that he would be getting some good business from ME.
But im doin a tuneup this comming week so Im getting all new plugs,wires,distributer cap and rotor. Will be getting blue aswell, that means I gotta get off my ass and paint the parts of the motor my previous owner painted orange to black now lol...
