Are all rear axle bearings "O" rings seals the same for all years? I know the '56 has only one ring but is this ring (rubber seal) the same as '57 and up with two rings on each bearings?
Also, does anybody have the part number for these rubber rings from GM or NAPA..?

Thanks,

Pierre

If you know the outside diameter and cross section diameter you can buy them from any local Ball Bearing distributor.
