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.

Group 24

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

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.
