    I ordered a replacement pinion seal (Omix-Ada 16521.01) for the Dana 44 rear diff.
    Looks like this:

    But after getting the dust shield/flange off, the current seal looks like this (not my diff...the image was taken from Google images):

    The outer portion of the seal has a flat steel face that's flush with the housing.
    Is this flat steel faced seal just another variation of a Dana 44 pinion seal (1st pic), or did I get the wrong seal?

    You likely have the correct seal.
    The existing one is built different with the seal sandwiched between a inner & outer shield, the replacement is a single layer of metal with the flexible sealing surface fused onto it. I have used several single layer built seals with acceptable results. The original style can likely still be had at several times the cost of the omix unit.

    Inspect the pinion shaft for a groove that may be worn into it from the old seal.
    Install the replacement seal with the garter spring towards the fluid side of the differential.

    Thanks for the reply.
    That was my guess, and after looking at Morris, Walcks and other sites' referenced seal, they all looked like the Omix.
    I went ahead and installed it without issue.
