I went with this indented peanut style tank. I like the way it looks and it fits the Bobber style. It’s designed to mount from the bottom but after mocking it up where I wanted it the front mount would have been a little tricky to use with this frame design. So I cut the mounting tabs and welded them to the front of the tank, then drilled and tapped.
I cut the rear tabs as well and welded them in place. Pretty easy install.
