Hy 57chevydelivery, I could only find listings for a wheel/hub seal and a pinion seal for that axle. I will give you the wheel/hub seal numbers and dimensions, in case that's what you want. Wheel/hub seal dimensions 3.188"X4.625"X.5625", Napa p/n NOS31870 $29.99, Rock Auto [National] 6358 $21.79. If you are looking for the outer wheelbearing locknut with the rubber seal built in, those were a GM part and are no longer available, as far as I know. They were for grease packed rear wheel bearings, if you clean the grease out and omit the rubber seal at the wheelbearing nut, your bearings will become the oil lubricated type. Hope that helps.
