New trunk floor is my next project, I can take out the thin tin one and use it for a template for some thicker sheet metal and cross brace under it to support this bigger fuel cell and probably just one battery. Since the mufflers will be right under it I may insulate it with fat mat or whaterver, wont much of it show anyway. http://www.forabodiesonly.com/mopar/attachment.php?attachmentid=1714774039&stc=1&d=1418013314
