front wheel hub,bearings,and seal. all the books and manuals show a wheel seal for my 1941 1-1/2 ton gmc. but I have no seal. from the inner bearing I have a spacer ring fits tight to the axle about .125th thick same hight as the bearing with a bevel inside. then a tin spacer that fit the outer hub but has a gap not tight to the axle. about .040th thick and the outside edge has a small lip. than one more tin like dust cover ring fits tight to the axle and is round enough to fit over the hub with a lip. I see no seal.... please help
