The parts store gave you the wrong part(s). The "crush sleeve" is the spacer you took out. The new one should look the same, but without the deformation on the one end. The deformation is caused when the pinion nut is tightened to set the preload. Not sure what the parts they gave you go to, they don't match the Spicer axle used in the '59 Posi rearend either.
