I put a 24oz Dubro Tank in mine. I just got the dremel out and started cutting.....I did reinforce the cabane mounts when I built it back up. You could mount your 180 inverted if you don't want to move the tank. Also when side mounting the 180 you have to make a tunnel for the muffler to clear the firewall. None if this is hard at all. I think if you have a good look at it you could do it.
