I have a real tall 50 caliber ammo can, (19" tall, makes for a great armrest!) that's just big enough to hold my bi-fold lug wrench. You can use any size you like, they come in many sizes.
I had my CB mounted to the front of it, but just moved it to the new overhead tubes I added to my roll cage. It worked well on the front of the ammo can, but I just liked it better where I could read the channels without looking so far away from the road.
You can just see it under the steering wheel in this pic;
