i have a 3 gallon patterson tank and mounts i need to get rid of. It's a little dented up, but it should work fine. It didn't fit in my buggy, so I had to go a different route. PM me if you're interested. It's a $500 dollar tank new, i dont know if they still are in business or not, i had to buy the mounts off eBay, but its got everything there but a cap (a cap off of a spun aluminum tank or from the parts store fits, though). I also got a tank from muddmutt that someone custom made with an olberg filter mounted to it.
