Does anyone have any pics of the heat shield (I assume) that attaches to the exhaust manifold for the heat riser tube coming from the air cleaner to attach to? It’s missing on my ‘75, I’ve searched on here and can’t find any pics or discussion but may be because I’m calling it the wrong thing. I come from the Mustang world and that’s what they were called there

Better yet, anyone have one they would part with? Thanks

With the new terms, you might be able to pull up images of it online. I’ve seen them before.
It was changed however, between 72 and 73 if I remember.
Slightly different shape tube, and, if I’m not mistaken, slightly different diameter.

This is as close as I have in existing photos on my ‘76. Can possibly take more later tonight of the actual shield/stove pipe if no one chimes in before then.

Here’s a few more. Not an easy area to get into for clear pics, and this one is smog equipped - so more in the way than usual.

Here’s a few from a ‘73. Taken from firewall working forward gives a better idea of what the part looks like. Last one is more from above than the first three
