Crankshaft Rear oil slinger question????
 

During disassembly of my 06 V10 6.8 30 valve engine ,there was no rear crankshaft oil Slinger noted ... This part in my opinion is more like a dust shield to the rear main seal ..rather than a slinger !!
Never the less only two of my manuals show its existence could someone tell me if Ford Discontinued it as part of the reassembly??? I am finding little information about this part other than the special $97 to reinstall it ... Few Ford OEM parts suppliers even list it ??? None on eBay ....

Any input would be much appreciated
