I'm trying to get my wheels off, but I was suprised that the wheel nut is counter clockwise, and that there is a double nut for the dually system. So where do I find the square 13/16" tool to loosen these and what is it called?
Hy Steve-W, You are working with Budd wheels which use an inner and outer nut system for the rear wheels. The left side of the vehicle as viewed while sitting on the seat is left hand thread for the wheel retaining hardware front and rear axles. As Paul_WNC has said, search for Budd wheel sockets or wrenches to help you when working with this wheel mounting system, good luck.
NAPA sells a combination socket that works on both the inner and outer nuts. I've got one that fits my 3/4" drive impact wrench, and there's also a 1" drive type for the big commercial air wrenches. I've changed a bunch of those wheels with a big 4-way lug wrench and a 6 foot cheater pipe when I was doing maintenance for a very small trucking company. The boss was too cheap to buy air tools!

So just to give the last update here to close the topic. In january I ordered through Amazon and it got delivered a week later, so pretty good. got the wheels off and the progress can be followed in my Ratification project page.
