Knowing people that know how to weld is great

Had this horn for years. Finally got a k3. I’ve been busy with life and it’s time to get them out and put on my truck once I get it registered. Took them off my mustang years ago after I got it back from being stolen. They took one horn. So found this one on eBay for 30 bucks and a friend of mine fixed it for a 12 pack. Just going to get a 10 gallon tank and a second air compressor. It should sound pretty good. Just need a mount anyone have one for a good price?
