Any recommendations on mounting MotoHorn?

I have a MotoHorn in transit for my 2020 RT. It is a bugle style horn, perhaps 14" or so long. Does anyone have any recommendations on mounting one of these? I don't think there's room in the wheel wells, and I'm not sure if mounting on top of the steering arm mechanism will work.

You'll be the first. All I know id the newer models, especially the '21's require a dual snail horn set which is all that fits. Spyderpops has kits.
