Need help identifying seal between transfer case and drive shaft (see photos)

[Lehma1989]

I am replacing the automatic transmission seal (Where the driveshaft meets the transfer case). What I can’t figure out- nor my local auto shop is this small, additional seal that sits behind the bolt. (See photo)

Any help on figuring out a part number would be excellent!
