    SGB,
    I wanted to let you know it is a sure grip 741 case.
    Don’t know if this is what you have or not.

    I’m sure he will jump in when he can. I hope so he has been a life saver so far on this rebuild

    Cone or clutch? Dr Diff sells new spider gears with the shafts for the Dana clutch type. $175.00

      I believe the OP has a spicer style sure grip unit.

      Is the one of the 4 pinion gears that broke? How did you break it?

      Please post up a picture of the whole unit but I’m guessing it’s this style.

      If its the cross style as above mine may not work. Does anyone know if the spider gears are different between SG's and opens? This is a (broken spider gear) clutch type.

      Yes. All three, open , cone, clutch type use different spider gears and they do not interchange.

        This rear end came out of a 67 Barracuda

        Are the crosspins in ramp to ramp?

        The ends of the cross pins have a rounded side and a ramped side. The case halves have only a ramped side, the other side being empty. In order for the unit to work, the ramps have to be facing eachother.
        When you apply power to the pinion, it turns the case. But with the wheels tied to the road, the sidegears resist the turning. This causes the ramps on the case to ride over the ramps on the crosspins, forcing the spider gears into the side gears, which squeezes the clutches together and thereby clamping the whole thing solid, depending on how the unit is set up.

        So, in your pics; it looks to me like the ramps are not oriented correctly, which is why I asked.

        In Pishta's post, #11, they appear to be correct

        I have it the way it supposed to be the pointed end down and the opposite pointed end up. If this is incorrect then I’m truly confused.

        The V of the shafts go towards the V in the case halves. One faces down one faces up. Simple enough.
