Carter 2bbl air cleaner clamp
It’s hillbilly as can be but it actually works pretty well, I have made more than one. You set the stud in the middle and wrap the wire around it from each side in a loop and then bend it straight down the width of the tabs on the air horn with two 1/8 90 degree bends on the end. Paint bucket bails are the exact size of the retainer holes. Use a vice and channel locks and measure as you go, it’s pretty easy to make.
