If worse comes to worse, and you don’t need a factory one, drill an air cleaner stud and run a hardware or paint bucket bail through it and make one.

I suppose that would work in a pinch. I can’t see why something like that is so hard to find. eBay had a whole carb on sale for 50 bucks that had one,but that’s a bit pricey.
