I need a part number for the inner rear axle seal for a 53 6400 with a 2 speed rear end the one i took out is about 4 5/8" OD with a 3 1/8" ID hole and it is about 1/2 " thick. it has definately been in and out a few times prior to me owning the truck! this leaking seal would account for the brakes locking up every now and then.
Thanks in advance

That's what I did when the 48's seal went bad,
