    Looking at the wear on the shaft, the holes in the ring gear carrier is probably wobbled out just as bad, not much fix for that other than a new RG carrier.

    stock 12 bolt shim or crush washer

If the drive shaft is too short, that has nothing to do with the yoke being a crush sleeve or shims, that has to do with...
