The originals had only one 30 amp fuse housed in a holder on the back of the ammeter, as I recall. Are you replacing all the wiring with a new wiring kit? I think I and most here would recommend so doing since 82 year old wiring likely has been subjected to who knows what kind of wear and tear. The Shop Manual shows the wiring diagram. I think one is also shown in files available on the “Old Car Manuals” website.
I added electric wipers and turn signals to my ‘37 that a previous owner converted to 12 volt. For each of those additions I included inline fuses. Recollection is fuzzy now, but I think they are 10 amp? I also added a battery cut off switch I use whenever the truck is not being used, which can be months at a time. I know some of this is redundant and likely unnecessary but, stories of shop fires etc make the precautions worth the effort IMO.
