Looking for a Fuelsafe CB300

I'm hoping to find a good, used wedge fuel cell. I, too, am restricted to 13.75" between my base rails. A Fuelsafe CB300 looks to be my only choice, unless some of you have an ATL FC152 that has been successfully compressed width-wise without fear of damage, or a custom tank of similar dimensions to one of the above.

pm, email would be fine and thanks for looking! -J
