Hi Paul, As per checking, this item is for the 2013-2016 Mazda CX-5. You need to get one that matches the original part. To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

Check it closely, if you need two keep looking. I had no issues.

Hi Adina, thank you for reaching out. This item doesn't include mounting hardware. We suggest you get those from the local auto parts store or dealership.

Enjoy shopping.

Hi Scott, I'm glad to assist you. That should be an 8mm or 10mm nut diameter size. You can check local auto parts supply stores to get that mounting nut. I hope this helps. Happy shopping.
