Clutchee,
Here is the info on the hub socket that I use for my trucks. It is a Craftsman 2 1/8" -12 point- 3/4" drive socket (Sears P/N G-47789). The adapter is also a Craftsman 1/2" to 3/4" drive adapter (Sears P/N 4271).
When running the numbers: 54 mm = 2.12598 in. So clearly the socket is toleranced slightly larger than 2 1/8 inches or the hub nut is actually slightly less than 54 mm. Either way it works. This socket fits in the hub of without any fit issues (I have used it on 40, 60, 70 and 80 series trucks without issue). Finally, the reason I bought it was the rounding over of the stamped steel hub socket I had originally when trying to loosen a very tight hub nut and of course this socket has never had a problem with this (or anything except the purchase price as I recall).
Below are a some pictures that I took for your reference if you ever have a chance to pick one up.
