Hi Sean, As per checking, this item does not come with installation hardware. We suggest getting those locally through a local auto supply store or the dealership.

It's been a minute since I put these on our car, but I don't think they came with hardware. But unless your car has lost the little clips that hold it on there, you can reuse those. Just be careful when you're popping those off so you don't lose them.

The trunk lid supports for my BMW did not come with mounting hardware. I just reused the old hardware.

You don’t need hardware, other than a screw driver. Very easy to install!
