1940 Ford 12 volt battery

[RAF]

Converting my 40 Ford to 12 volt and looking for a battery with the same dimensions as a 6 volt so I can use the stock battery tray and hold down. Napa store couldn't come up with a match. Any ideas? Thanks.

Here's a photo of the Group 24 Walmart battery I use. Cost about $100. 5 year guarantee. You have to turn the battery so the (-) terminal is near the firewall.
I used a copper sleeve on the negative terminal post to make the cable fit tight. Works fine. Removed labels for plain look.

PS: I know that my battery disconnect is on the "wrong" post but, it works

RAF....is it a hassle to convert ? What's the toughest part of doing it ?

Not that hard to change over, had my generator and starter changed to 12 volt, added 12 volt regulator, coil, light bulbs, and voltage reducers for gauges. There is a lot of information on the changeover if you search the internet.
