The Ford hub nut tool works like a charm but you DO have to "alter" it. I think Kenny went over that in his instructions, but if he didn't; you have to grind off two of the four "prongs" of the Ford tool leaving two of them opposite of one another, then you have to grind the existing two prongs thinner (grind from the outside of the tool towards the center). Here's mine:
If you had more time I would gladly send you mine, but it sounds like you want/need to get this done today.
I'm sure the screwdriver and hammer work well, but I was just a bit paranoid about whacking my hub nut with a sharp object.
