Knowing my Ford mounting nuts were swollen, I searched until I found these. 4X4 with 18" rims. They fit perfectly, close to the OEM spec rim. In conclusion, I decided it's worth beating off 5 puffy eyes to install. You really should get them, not cheap but quality product. I also bought a CRAFTSMAN Deep Impact, SAE, 1/2" drive, 13/16" drive. The bushing fits perfectly and grips the entire length of the collet nut. Socket bought here.
