Gotta question--
 
I put a 5 gallon fuel cell in the trunk of a car, it doesn't need a roll bar yet,I was going to keep the OEM rear seat, but I know I need to install some kind of firewall between the trunk and the interior. What thickness? I wanted to use aluminum since I have access to some, but I need to know the legal thickness required. I know you guys would know.Thanks!!
