    Correct water pump gaskets?

    Guys,

    Getting ready to bolt on the WP and noticed the gasket provided by the WP restorer doesn't match the water pump profile on one side. It clear it will work but it will result in extra gasket sticking out. My question is, is this supposed to be this way? or did the factory have two different style gaskets for the two different sides of the WP? If needed I can trim one of the gaskets down. I attached some pics if that helps.

    Thanks
    Mike

    It's been this way "forever-and-ever". GM never offered a 3 hole gasket in SERVICE. Only the gasket style you pictured has ever been available from GM.

    Now, the question arises if the engine factories used a 3 hole gasket on the left side. All I can tell you is that my very vague recollection of this on my 1969 when it was delivered to me is that the left side gasket was untrimmed and had the exposed hole. However, my memory is very vague on this point.

      Mike, I generally trim the gasket with a razor blade. I myself think its looks sloppy with the extra gasket hanging below pump.

        Thanks Ed. Do you know if it is something the judges are looking for on cars they are judging?

          Mike, highly unlikely, but never say never, you never know.
