Review on Spectra Premium Industries Classic F1B by Tim Pulse

Ordered 75 Ford F250 - F1B rear gas tank. This tank does not fit between the frame rails. The frame rails are 28 inches apart and the tank is 33 inches apart. I called support and got ABSOLUTELY NO HELP. All they could tell me is the reverse size, which is about 27 inches to fit in the frame spars, but with the fill tube facing the back of the truck instead of the side of the truck where it should be. And what do I have a hole in the bed for, so now I think I'm stuck with a tank I can't use.
