Can someone help with a Piper P/N please.

PA28-181.

Trying to find a good P/N for the oval shaped scat duct that connects the inner half of the exhaust riser shroud to the carb heat box. I’ve read that some of the custom duct companies do a nice job with these? A breakdown of the carb box area would also be great if anyone happens to have it. Not sure why my parts book isn’t showing this. Thanks

There it is. In the 2nd pic. I actually saw that figure initially, but overlooked the item due to it having a partial drawing. Expensive little hose. Thanks Bell.
