Anyone know of a aftermarket battery holder/tray that will fit and where I can buy one? | | | | | Joined: Sep 2006 Posts: 3,596 'Bolter | | 'Bolter Joined: Sep 2006 Posts: 3,596 | Summit Racing, Speedway Motors. Most automotive after market supply houses offer them. Pick up a copy of Rod Action or Street Rodder magazine they advertise heavily in there. | | | | | Joined: Oct 2005 Posts: 4,249 "Hey!

I can't decide whether to put it on the firewall or on the inner fender. | | | | | Joined: Mar 2008 Posts: 1,775 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 1,775 | I've seen guys pull the batt. bracket off the frame and mount it on the firewall. Grinding some rivets may be required. I've also thought about putting it under the seat. Lots of room under an oem bench seat. | | | | | Joined: Oct 2005 Posts: 4,249 "Hey!

Seriously, what's wrong with the original location? I know they moved them under the hood in 54 on the firewall, but I find that location awkward looking. Another aspect of moving a very heavy item further forward takes weight off the rear wheels. I know its only a few feet, but it makes a difference. This is why hotrodders move the battery to the trunk. I have been stuck on a sloppy wet, perfectly level muddy road in one of these trucks. They need more weight toward the rear.

They need more weight toward the rear. that's why they have that big 'tray' on the back, to carry weight  Doug - you could simply get a battery tray from one of the later years that had them originally and paste it under the hood - used is cheapest!!

Regular batties give off hydrogen when they charge. I've seen regular batteries explode during charging (and splash acid everywhere), so unless you buy a battery designed to be vented & vent it, I wouldn't put it in the cab.

That said, I see no reason to remove it from it's original location on an AD. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Millions of Volkswagens ran billions of miles with the battery under the back seat.

I wouldn't put it on the inner fender as it's to heavy, the inner fender is not strong enough to handle the weight of a bouncing battery. Mike B  | | | | | Joined: Oct 2005 Posts: 4,249 "Hey!

I'm not at that point yet.
I kinda don't want to see the firewall tear out, either. | | | | | Joined: Jun 2005 Posts: 1,756 Shop Shark | | Shop Shark Joined: Jun 2005 Posts: 1,756 | [quote=johntsmith]When I moved the gas tank to the rear, I put a dry cell behind the seat with a cut out switch.
Me too, use a Optima battery seal it up and forget it. | | | | | Joined: May 2005 Posts: 8,878 . | | .

I've made a whole bunch of changes on my truck and leaving the battery where it was is a no-brainer, it's actually a nice handy place for one. I didn't have a good original box/tray and wanted a little larger one so I'm using one of the stainless drop down boxes sold by the aftermarket/hot rod shops for these trucks. In my other truck I made the original longer by moving one bracket back and making a new bottom.

I didn't want the battery under the box or bed, or behind the seat. A friend of mine had the battery on his AD behind the seat, it caught fire while he was working under the truck in the garage one day and did a lot of damage to his truck. I'll never have a battery in the cab. | | |
