1986 Cutlass Supreme 3.8L - PCV valve hose

Anyone know where I can but a PCV valve hose for a 1986 Oldsmobile Cutlass Supreme with 3.8L V6? I'm looking for the hose from valve cover to air cleaner. I've pretty much exhausted google search with no luck.

If its a 25505469 you're looking for, there is one on EBay.

(While a Buick 3.8L has a very small block, its a non-Olds engine.)

The thing between your fingers in the picture is a check valve. Usually those are between systems that
need vacuum even at WOT(wide open throttle.
