I've had the battery mounted on the firewall of my 48 before (when it was subframed) and it sucked big time. Along with being an ugly zit in there it blocked access to the right valve cover on the V8.

This go around I am thinking seriously about getting a battery like the Audi 5000 we had and I think my 2000 Cad Deville has and mounting it in the space behind the passenger seat in a box. I don't have a tank back there though and on that model of battery there is a built in vent tube that runs through the floor board to vent the battery.

Looking it up the Audi had a Group 48 battery that was basically 11 inches long 7 inches wide and 7-1/7 inches tall. The Cad takes a group 79 that is 12 inches long 7 inches wide and 7.3 inches tall and has side posts. Neither is cheap by any means but either should fit and have the poop to start most engines.
