    But how do you know which carrier you have? I see it says series 2 is 3.08 and lower so would that mean if my gears are 3.08 or under I have a series 2 and if it's over I have the series 3?

    There is a build tag that is attached to most rear ends that will give you the specs.

    Would this fit a stock 10 bolt from an 87 trans am or would I need the series 2

    Asked by: Smarth45
    This fits a factory, 3 series carrier.
