anyone ever change an input shaft seal on a w210 (98 E300) rear differential?

I purchased a new seal and I'll swear it looks like the new seal (revised p/n) has a flange that requires you to install the seal from the inside of the differential. I'm going to review it more tomorrow but was wondering if anyone has been through this procedure.

Manual shows the seal installation just like the earlier ones. From the driveshaft side. Something does not look right with the new seal.

Looked at it again today and found (remembered it by reading on here) the vent plugged up. Cleaned it up and reinstalled and I'll continue to monitor the area around the pinion seal to see if the leak is resolved.
