You are so right. What looked like the face of a bearing was really the extra seal. I gently peeled in out with a small screwdriver and that revealed the large nut and locking nut behind. I'd still like to know what year the rear end is. The last tags on it are 2000 and it was used as a movie prop according to the last owner so I think it has had some work done on it. The rearend looks much newer than the rest of the truck and previous owner said it easily cruised at 55 mph??? Here is a picture of the hub and braake drum if you hadn't seen it. https://picasaweb.google.com/Bompajohntaylor/1947HubAndBrakeDrum?authkey=Gv1sRgCJLrmv--m7ew6wE#
