That’s a very interesting, and factual, table. It does appear that 3/4 ton 4WD and 1/2 ton 4WD frame are the same gauge, but I’m surprised to see that 2WD frames are a little lighter construction.

Do you know where I would find the equivalent table for my ‘75?

That will give you something to do while you're on a Corona lockdown.

Keep in mind too that the spec is for the frame rail. From the pics I've seen here it looks like some of the crossmembers are different between a 10 and a 20.
