    I want to remember they offered a variant of the G80 since the 70s??

    Yeah, the G80 is by far the best factory offered diff on the market.
    It's bad rap for "blowing up" is almost entirely undeserved and caused by people just plain abusing it. For example, laying into the accelerator in a one wheel, low traction condition, causing the diff to engage extremely hard.
    Though the biggest killer is non-stock, big tire, off road use where it is subjected to torques well outside it's design range.
    Even then I have to wonder what people are doing to them.

    My own truck has it's original G80 with very high mileage on it and even though it's now facing HP and Torque numbers way higher than stock, it's last inspection showed it to be in mint condition.

    In bad weather, I wouldn't want anything else. In fact in many conditions a 2wd GM with a G80 handles better than a competitor in 4wd.
    In the snow it's like a damn snowmobile.
