Foxbody rear firewall

Foxbody rear firewall
Decided to move my battery to the trunk today in a continued effort to clean up my engine bay.
Then I read the NHRA rules for batteries in the trunk. Hmmmmmm, now I need a rear firewall, I've seen them for newer foxes and complete rear seat deletes, but I'd really like to keep my back seat.
Any suggestions.

All you should need is a battery box. There are a few members on here that are NHRA compliant and do not have a complete firewall for the rear. I believe that is only needed when a fuel cell is inside the car.

All you neeed to do is to get a 'accepted' batery box for the battery,
Taylor, Moroso are just a couple I can think of that are 'approved'.
You'll also need a master switch for a correct installation.
DO NOT cheap out on this part.
Flaming River makes a good one as does Moroso.
I made my own battery box out of .120 aluminum as well as the box that my fuel cell is in.
It has passed tech many times at NHRA events.

Is a plastic tube that vents poisonous gas from the battery cheaper than a firewall? I think not.
The vent tube is to prevent gas from building up in the passenger cabin if the car is left in a garage or some storage spot with the windows up for a long time. Unless you completely seal the firewall with welds or sealant... gas will still permeate into the passenger cabin.
At least I think so.

Thanks man - just what Im looking for
BTW - I ended up @ 120mph on your old springs/ arms. Got taken out a few days ago in favor of coil overs. BUT - its now being moved to a 347 based hatch. Def. a good buy.

Okay, you do just need a battery box. I have one like this in my hatchback without a firewall. It's been teched and passed, so no problems.

One thing I want to mention though, is that I think (don't quote me on this, you should verify for yourself) that if you have a sealed battery like an Optima (that's what I'm running) you don't even need a sealed and vented battery box.
Had I known that before I bought my battery box, I would've used this one:

For whatever reason, it seems like I'm in my battery box quite a bit... I wouldn't have to deal with the wing nuts on the battery box if I had an open battery tray like this one.
I guess it's just user preference, but there's my opinion on the topic.
