    Fred, Do you know the condition of the posi unit (cones)? What kind of mileage does it have on it?

    Sorry,Didn't keep a record of the mileage on the car. Also have no knowledge of cones, so could not tell even if I was looking at it. Sorry.

    Now that's interesting, I've not seen any drawings in my manuals other than the cone-type posi system in 8.2's.

    When I changed the grease after it had been sitting since 1984 it looks like a standard clutch pack and my posi rearend out of a gs 455 automatic car with 364 gears also has the same set up but did not take pics when I put new gasket on cover I can this winter
