I would polish that with some very fine emery cloth then change the position of the seal in the tail housing so that the sealing lip is riding on a different portion of the output flange surface.  You can also remove the spring on the back side of the lip and tighten it to make it seal and compensate for the metal you took away with the polishing.

Thanks Sherman - I was wondering about doing something similar. There are just a few tiny grooves I can feel w/ the edge of my fingernail where the old seal was riding. Someone must have found a way to fill these grooves and/or sleeve a flange. I really don't want to shell out $189 for a new one: https://www.ebay.com/itm/BMW-Getrag-245-5-speed-E21-320i-gearbox-transmission-4-bolt-flange-RARE/274311472884?hash=item3fde3ce6f4:g:-fcAAOSwhKZeFkzc

There isn't going to be anything that really fills the grooves without wearing away unless you were to weld then machine it.  Sleeving would also be cost prohibitive compared to the price of a new part.  Labor prices have gone up so much that rebuilding some things is not logical anymore.  If your output shaft seal was pressed in so that it was flush to the tailhousing then you simply have to see if it can be installed further in or left slightly out so that it is riding on a surface that is the original diameter.
