If the hub nuts are round with slots in them for a spanner wrench, I've fabricated my own wrenches with a piece of pipe with short pieces of key stock welded to it. Some of the nuts have four slots, and others have six. Either drill a hole in the pipe for a long tapered punch as a lever, or just use a pipe wrench. There will be a locking washer between the two nuts, with tabs to bend down into one of the slots.
