Mr. heater mounting Question

[CAO]

My old Mr. Heater finally broke beyond repair and I bought a new one. The problem is the new one doesn't have the metal slot attached to the back of the heater so I cannot mount under the bow of the drift boat on the metal hockey stick looking thing, I have the tank in the back of the boat and it's plumbed to the bow.

Any suggestions on how to mount my heater? Thanks in advance for any input. Hopefully I was clear in my description of my problem.

If you haven't used it yet trade it for a Mr heater / Cooker and it will fit that is the difference
