Regarding fuel cells in a track-prepped Foxes and SN95s: what do most of you guys do? Fuel Safe offers a "bolt-in" solution, but I recall not seeing many under track rat Foxes and SN95s. Want to say that most people cut out the trunk floor and install a "universal" type cell rather than a bolt-in type unit from Fuel Safe. Show me some pics of what you guys did, if you don't mind!
