Hy Bubba the Emt, please remember to tell us what year of truck you are asking about in your posts, that way we don't have to go and check your profile to find out what you're asking about. Fel-Pro numbers for the cover gaskets are, for single speed rear end RDS 4062, for two speed rear end RDS 5050, and they are not the same as one ton gaskets, hope that helps.
