I know that bedsides for '51 trucks (and likely 47-55.1) were 16 gauge. That's what I used when I patched mine. I would guess that your '46 also used 16 gauge metal. If you have a caliper or micrometer, you can check the thickness of the existing metal. 16 gauge should be darn close to 1/16" or 0.0625 inches thick.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
