3/4" to 1" towbar adapter bushing

That's a good point about the adjusting pins being 3/4". That leads one to ask why the different size in feet at all on the trucks, after all if they just used 3/4" on all the trucks that would reduce the number of different part numbers in the inventory. but then this popped into my mind while typing this, my guess is it's the size of the lifting shackles that determine the size of the feet. ( I wouldn't want to be anywhere near a deuce when it's being lifted by 3/4" pins)

Air lifting is more strenuous than towing.

I had a structural engineer do some quick calcs at work. He based the rating of the 1" pins off of 48000 lbs (I gave him the wrong number). And he said if the 1" pin is rated at 48000 than the 3/4" is at 24800. I have his calcs, i cant decifer.
