I recently purchased a set of rally wheels and want to put new lug nuts on when I put the new wheels on. What are the correct sized lug nuts? I am finding answers that give me two different sizes when I do a google search. Which is the correct size and is there a brand that is of better quality as far as coating and durability. Or are they pretty much all the same? The searches I have done come up with these sizes:(1/2-20) or(7/16-20)
Dave is correct on the size. Cars or Mitch Romanowski may have solid ones and the parts place has these, 1970 Buick Skylark/GS/Regal/GN Parts (thepartsplaceinc.com)
