Far as I know Milleniums are only built with one offset. Thought you were talking about adding a spacer. They fit like they were purposely designed to fit. Which they were.

My bolts are a 1/2 in. shorter then stock. 3/8 might be better. Remember it is easier to fix too long than it is to fix too short.

Enjoy your box of brand new lug nuts. You are not the first to be a proud owner of useless nuts.
