This is the cover gasket that is used on 1947-63 Pick Up Trucks with the model 53 rear axle. This is the style rear end that has the inspection cover on it and must be checked from 1947-55 to see what axle is in it. The other model axle is the Timken style that is the 2 halves of the housing bolted together (No inspection cover).
