Every one I've ever seen is like the ones pictured all the way from Sweden.
Like Mats I had to grind the heads off BOTH of my bolts in the bed to drop the tank. (It looks like Mats only had to grind one off)

After I had my tank leak fixed I had to get it mounted again.
First I reamed out the holes through the tank to clean out the rust, clay, sand, salt, and what ever else was in there.
I then tried to coat the inside of these holes with POR-15. I also coated the outside of the tank with POR-15.
Then I had to make new mounting bolts because I destroyed the heads on the old ones and didn't even attempt to unscrew the original fasteners. To do this I bought some 1/2" threaded rod and short 1/2" carriage bolts with the same thread. After a little measuring I cut the threaded rod to the length I needed and welded it to the carriage bolts. Then I just used 1/2" nuts and 1/2" fender washers under the tank to hold it in place.
It has been hangning there now a good 10 years.
