Howards Hog Horns / Trumpet Horns - Anybody have them?

[kingpin]

I have a set of trumpet horns from Howards Hog Horns, and I want to remove the left side "hub cap" and mount them between the jugs.

However, rather than invent the "wheel" all over again, I was hoping somebody might have gone through the pain and be willing to share some expertise with me.
