The battery access for these model trucks, going back I believe to at least 1937 requires removing the floor board. It is a real nuisance too, especially trying to avoid scratching painted surfaces inside the cab. I modified the new floor board I used on Sparky to make it only necessary to remove about half of the board. I now can access either the battery or master cylinder by removing one half or the other depending on which part needs maintenance, with less misery.
The battery tray shown, I think has an extra brace that I don’t recall off hand seeing on my ‘46. But, as shown should work fine. I will try to remember to check mine tomorrow.
Interesting! So it isn’t even possible to remove the battery from underneath the truck!
My floor got cut out to allow a regular size battery to fit through and a cover (maybe from years later) was added.
However, the access hole for the master cylinder isn’t in the correct place either so my floor must be entirely different either way!
If you have a picture of the tray installed that would be very helpful, but I know it’s hard to access.
