Building a Duster body with the battery in the trunk but will be using a stock fuel tank - no fuel cell in trunk area. Is a metal firewall still required since the battery will be in the trunk?

How did you mount your trunk mount battery - with the posts parallel to the qtr panel or perpendicular? Concerned about uncovering the cells under hard acceleration, thinking perpendicular is the way to go.

Also installing an 8 pt roll bar. I also want to reinstall the rear seat. Any tricks for squeezing it back in there once the roll bar is in? The lower cushion might go thru the sides if the pop out windows aren't installed - not sure about the back seat rest. And no, NO ONE will be sitting in the rear seat, period - just doing it for looks, don't want that cavernous empty space back there. A little sound deadening, too... I plan to have the rear hoop support bars bottom out just at the edge of the package tray, which means they go almost to the tail lite panel!
