You're not going to find inch-thread lug nuts with the external threads on them
Jerry, that's not 100% true. I'm not sure who makes them, but they are available in a 1/2"-20 thread. They do have a 7/8" hex, and use the larger full size truck lug caps. I have a set on mine, found them at a swap meet from the same vendor I got my '94-'98 style center caps I'm using.
