Go to, click on "site map", click on "axle codes"....part way down the page are pictures that show how to ID the different size rear ends by the casting identifiers.

The Casting #'s you posted won't lead to any kind of ID, the only codes that would do that are stamped into the forward side of one of the axle tubes.
