Not sure buddy
You may find the results to your question by going to there website and go to, "View Inventory." Then type in the the make and model. There's no guarantee they have one though. They are working on updating their inventory. But once you've found the car you need there's a a link at the bottom that allows you to select "Parts Price" or "Compatible parts." Select "Compatible Parts" and fill in the page. Once you've done this, it will list all the cars that have the same lug pattern, offset and hub bore as your 08 Grand Marquis. Good luck. I hope this helps you. I don't work there, but I'm in the yard almost every week.
