1972-1979.5 Dodge Model 70 rear axles had a Bill of Materials (BOM) number stamped on the rear side of the right axle tube and/or a BOM tag retained by 2 of the differential cover bolts. BOM numbers for these axles will start with "603". Each different BOM number signifies an engineering part change which may be minor or major and may involve one or more parts. The dash number indicates the axle ratio and differential type (open or locking). Unfortunately, the tags are often missing on trucks that had prior differential service.
