I had bought a set of date coded from Ames just before the car was hit and they were excellent. And they defiantely did not have Camaro anything on them. I would call ans ask about that, I wonder if they somehow sent you the wrong stuff. My set came in a clear bag with a heavy paper thing stapled accross the top. And you have to tell them the year and the quarter your car was built to get the right plugs etc. Both ends were dead on with an old original set I had been given. The only reason I don't use them now is due to the MSD plug & play ignition and need a heavier wire as the Taylor wires I use now...
