    Dave,

    Thank you for this information. My fan has the 2-3/8" center hole and 3.0" Bolt Circle Diameter. So it looks like it is GM#3789562.

    Was this fan ever used on Corvettes? If yes, what year and application?

    I will still install it on my 1967 replacing the 7-blade fan for judging. I'll take a few points deduction for originality.

    Rocco------

    The GM #3789562 was used for late 1963-1964 Corvettes with C-60. It was also used for late 1966-67 Corvettes with 327 and C-60. It was discontinued from SERVICE in May, 1972 and replaced by GM #3931002.
    In Appreciation of John Hinckley

      I have a 68 AC only fan blade. I actually collected a few of them thinking it was for my 69 435 hp 20 years ago.
      Found out it was for an AC car.
      Blades are 6 1/8 in length and measured across center blade to longest center blade is 17.75 inches
      it is stamped H and front and flat rivets

      The other correct blades I have which is the 66 front and H, these blades are 6 inches in length and correct for the big blocks
      you have my email so send one to me.
      Thanks, grant
