Correct lug nut size

I know this might be a stupid question but on a 13 14 GT500 aren't they supposed to come with 21mm lug nuts on the performance pack wheels? My 12 GT came with 21mm lugs and when i just purchased my 14 it had 19mm lugs on it which I thought was odd, I know the previous owner had like 3 sets of wheels for this car I am just thinking he put the wrong lug nuts back on when he traded it in to the dealer.

19mm (3/4") is just a smaller diameter hex nut size. Factory is 21mm (13/16").

The thread pitch is 1/2"-20.

I've used 19mm wheel nuts on my stock PP wheels and Forgeline wheels no issue.
