I just put up the link before someone pulls the trigger on $140 worth of simple nuts, and a return is easy if they don't work. Then for the lug wrench any Toyota/Lexus used piece might work depending on rim, or if not a thin wall 21mm socket and breaker bar are needed to complete the conversion. Enjoy the peace of mind of never getting stranded for such a stupid reason. These cars have 1970s problems.

 

I actually went through this scenario a number of years ago, when I owned a Lincoln LS. The lugs on that car were essentially the same as the Jag lugs, and in my case, since my wife was driving the LS year round, I was swapping the winter/summer tires twice a year. This was obviously hard on the lugs, and I was concerned about them deteriorating.


Back then, there was an organization known as the Lincoln LS Owners Club (LLSOC), and one of the members did a little research, finding that a certain Mitsubishi lug nut was a better piece. MANY of us swapped over to the Mitsu lugs, with good results, however they were also a 21mm hex.

Dodge used those same lug nuts on a number or cars at the same time. I ordered a full set, they arrived, but were shipped our from a variety of different dealer parts departments. I took that to mean that they were a remainder or Dodge parts that were no longer being offered.
