    limited slip you have no control over what it decides to do which is usally not much

    IIRC Gm never put any type of locker/posi in fronts, other than certain military trucks. Anyways, what you have is probly an Eaton posi, as GM didn't put govlocks in them yet, not till the early 80s. It's a posi, so if both tires are on slick ground, they will both spin, but if one is on pavement and other on dirt, the one on dirt will most likely spin while the other does nothing.
