    12366984 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Hard to beat an OEM head gasket I ordered these head gaskets as an exact OEM replacement. I only needed the right side. It fit perfectly. The guide pin was a tight fit and held the gasket perfectly in the right location. The thickness perfectly matched the original gasket. The JEG's price beat most competitors and the shipping on the order was free.
