Hornblaster Outlaw Mounting

Hey guys, I am new to the forum and I don’t know if this is the right place to post this question, but my friend just gave me the set of black Hornblaster Outlaws for my truck. The problem is that they will not fit anywhere on my truck besides the toolbox. Have any of you had success mounting the horns in the toolbox? My problem with the whole thing is having to drill a hole for the air line in the toolbox because it is a really nice toolbox and I want to be able to fix it with some JB Weld or something similar if I ever decide to take them off and it appears that the hole for the air line would be pretty big. Any recommendations? If is worse comes to worst I will just go ahead and drill it, but if I don’t have to that would be preferred.

Thank guys!

horns can be mounted on the outside of the box. I have my whole setup in the box, and the horns under the box.

Welcome to the forum. How about individual manifolds so they can be mounted in different spots?
