I am in a bit of a pickle. I need some part numbers for the front outer wheel bearings on my 1949 6400. I have tried crossing the hyatt numbers, but no one can help me. Anyone have those numbers handy. Also, do I have to replace both inner and outer because the new bearings are not the "barrel" design? Thanks guys......Also, don't be an idiot like me and assume the last owner of your truck had repacked the wheel bearings!
