[62bagger]

I had the same question when I moved the tank on my 62. I used a 64-mustang tank from Tanks Inc. It is slim enough that it does not hang below the bumper. I had to make a mounting plate because it was not wide enough to fit the frame rails. Unfortunately, I am not really good at documenting what I did but I do have a couple of photos of the finished tank. I hope this gives you an option for your project.
