    It appears to be a 14 bolt semi-floater with a Gov-Lok. /forums/images/graemlins/thumb.gif

    SF 14 with a Gov-Lock. Not a great locker by anyone's definition, but not as likely to explode in the SF 14 as it would be in a 10 bolt.

    Might want to re-read what I posted...

    It's only less bad than the 10 bolt version.

    Rotate the carrier until you see a bunch of numbers stamped on the edge of the ring gear. Some brake Kleen will make things more legible. Post the numbers here and we'll tell ya what they mean. (I'm betting you have 4.10's though)

    The Gov-loc was the optional carrier, prolly half of the trucks out there got them. Maybe a little less...

    i cut up an 85 c20 burb with 9.5 and grenade lok in it, got an 83 longfleet K20 coming and its got a 9.5 also, possibly grenade lok too

    you definitely have a 9.5" SF 14 bolt with grenade lok in the pic, very common

    good luck
