Air Intake Part Question

I am restoring a 1981 Toyota Pick-up (22R). My engine air intake system is missing the "Auxiliary System"? It's the arm that comes off the air filter housing and runs into the grill... attached to it is the HAI Diaphragm that connects into the Exhaust Manifold.

Does anyone know the name of this hose-like part?... or where I might look to order one? I've heard about Toyotageeks.com ...and I am going to search a few junkyards but I was curios to know if anyone had other suggestions.

I tried to include 3 pics to clarify my post but for some reason it has posted 12 and most of them are error messages so it's probably best to ignore the pics.

Cheers!

Probably just air cleaner housing with auxiliary HAI
