Thanks a bunch Jerry, that's the best info I've got so far. I have a number of rear ends here and I will practice taking one apart before attempting it on the one I need.
That being said I do have a 4.10 here that I'm told needs bearings that I would trade for a unmolested 4.57.
If the O.D.S.S. group will be attending the Manchester VA. event in Sept. I hope to join them there , I can bring it with Me.

Is this posted in the wrong forum?????? should it be in the parts wanted forum ??
