okay so, i talked to someone from scca about fuel cell regulations and apparently i need to enclose my fuel cell for it to be track legal. now, id like to have a tank that fits directly into my spare tire dish and rivet a piece of sheet metal over it but i cant find one that is low enough profile. so what do you guys think? should i cut into the floor? or does anyone know of a good 10 gallon tank that will sit flush in the spare tire dish? any thoughts would be appreciated.
