If it's not raining tomorrow, I'll check the nut size on a 46 2-ton, 48 1-1/2 ton and a 50 2-ton.
1-1/8 socket comes to mind for the nut size, but that is just a guess.
Also there are regular nut size for a standard thread and a heavy nut size for the same thread.
So take the whole set to make sure, so you can do what you have to do.
