Firewall Battery Shelf?

I just plain don’t like the battery located under the floor and I want to install a simple shelf for it on the passenger side firewall inside the engine compartment. The flywheel is relatively flat in that area so something pretty basic would do the job I would think, I’m looking to see if anyone has some suggestions for this.

I don't understand what the flywheel being flat has to do with putting your battery on the firewall??

If you install a split lower floorboard, it makes having the battery under the floor more livable. You only have to remove half the floor to get to the battery.
 
Master Cylinder.......Even having to remove "half the floor" seems like an unnecessary pain in the backside...especially as I have padded carpet front and back to cut noise. I can roll the front carpet back to access the battery and have enlarged the hole...but having the battery easily accessible for jump starts, etc. is still desirable. I have toyed with putting it behind the back seat in my '30 Tudor (with a third...back door) ...but that is a VERY long cable run...and I would still have to remove the trunk to open that door!
 
For jump starts, I would connect the cables to the starter terminal and a ground under the hood, not on the battery.

Exactly, no reason to lift the floor to jump start. I have even seen some install a brass tab on the starter terminal to connect to.
 
With a EVR in my generator I can’t remember the last time I needed access to my battery! Wait it was for checking water level in the battery which was easily done through oblong hole in the floor after flipping back the mat and insulation . Once I needed to disconnect the battery for starter maintenance again after flipping back the mat at insulation through the oblong hole. Sitting on the running board then a little twisting mostly using my right arm ain’t a big deal ! Once every 5 years I need to remove the floor board to replace the battery which is a pain .
Mounting a battery on the right side firewall you have the gas valve and line, the GAV rod that may be low enough and not a problem , high heat from the exhaust. Placing a battery on the lefthand running board then a few feet of extra cables hidden in a picnic basket might be doable ?

It's been done lots of times over the years,but on the drivers side.The gas bowl is in the way on the riders side.I just don't see a need for it,I don't have to access my battery for years at a time,usually for the life of the battery.
 
Early 50's chevy's had battery trays on the firewall.
A search for 49-54 chevy battery tray will show several options.
 
My 31 coupe once had the battery on the firewall driver side, Witnessed by the deep acid caused corrosion pits in the firewall.

I agree. WHY do it!
 
My current SW project came with the battery mounted on the firewall. It has additional supportative brackets on the other side of the firewall.

The car was supposedly used as a Taxi and I figured it made sense for easily servicing the battery.

I restored the battery holder and will probably leave it that way.

No corrosion evidence on the firewall.

Modern batteries need little to no attention, so why would a relocation of the battery to the firewall be advantageous? For connecting a charger or jump-starting a Model "A", access to the starter motor is all that is necessary.
 
My old pickup came to me with an early, store-bought battery holder for the firewall. Possibly the 1940's? I have many other irons in the fire, so I left it there and it IS way handy. I ran two new "00" gauge black cables, one to ground on water inlet bolt & other to starter. There is no corrosion around battery either. The truck is mostly unrestored.
 
I have a great firewall battery tray that's virtually brand-new. Very heavy duty and sturdy. It's for a '28-29 two-piece firewall with a ledge across the top for bolting to the upper and lower cowl flanges, but it can be adapted to a '30-31 firewall. $25 plus postage.
