    Hey,
    My 64 has 273's, front and rear. Take a ride to a bookstore and look in the "Chevy by the Numbers" book available for your year. It has all options and colors.
    Good Luck

    Rear end options are early 70's. Try to find a 72 and you will be set for an easy disk brake upgrade in the future.

    The 1965 1/2tons could have three different ratios.They had a 3.07,a 3.73 and a 4.11.
