350 Manifold Heat Riser/Shield

[Mac's-72]

This is my first time posting a thread. I have an all numbers matching 72 Cheyenne but as the case over the years, a few things were changed. I have everything back completely original with the exception of the radiator over flow tank which will be here today. I need to find the manifold heat riser shield that goes on the drivers side manifold to connect the hose to the snorkel of the air cleaner. I have the hose but not having any luck finding the part that goes on the manifold to receive the hose. Does anyone know where I could find a good used one or someone that sells good reproductions?

Thanks.......
