fuel cell

Just looking into putting a fuel cell in my demon. I would like it to sit flush with the trunk.. removing spare tire well, I would like to see pictures of other A bodies with fuel cells and where you bought it and $$$. Have looked in summit but they list so many of them and most are an above mount tank not a flush mount tank. My spare tire well is too weak to support oem tank and I know I could fit the sheet metal but I like the look of a aluminum fuel cell! Thanks Jared
