Well idk if this is uncommon or not, but my truck has a Corp 14 with 9/16 wheel studs and the front is 1/2. Any info on that would be nice. But to answer your question the lug nuts are dorman pn 611-161 for the rear and 611-222 for the front. The caps fit ok, the fronts are a little loose so maybe a different pn would work better but this is what I found. I got them from carquest. I hope this helps someone.
