351W swap in my 77 supercab. There is an elbow in the valve cover, with a hose stamped E9UE-6A886-AA. PCV plugs into that, then another hose, F4TE-6A664-BB, runs from the PCV to the upper. Local dealer says discontinued. To be honest, i wouldn't mind getting everything, from the valve cover up to the Plenum.

Hey Bill.... HELP

 

You can use fuel hose for most of this stuff. Napa sells a variety of elbows for different diameter hoses if you need to get creative.
