Lonnie,

Are you interested in wheel/drum-hub-bearing information? I think that I have used Task Force front hubs (drum-hub-bearings) on my 1954 1/2 ton. It looks like at least the 51-57 hubs are the same part number(3694768)

I really I do not know, but maybe these front wheel bearing years might help you. If you are looking for other information, I'll delete this.
