I don't want NAPA lug nuts. They charged me $30 for 5 the last time I was there. Plus I want them in black.

 

Did, you try going to any parts store website, most of the will have the dimension of the part. Or if you are buying them online, any decent supplier will allow you to search by make and model.

Simple google search.

 

Make sure you check with the company that you are getting the wheels from to see what kind of lug nuts the wheels need. Most likely conical seat, but there are some other types.
