Floor mat retainer clip is available as Nissan part

[DennisN]

My OEM carpet mats wore out. There's a hole in the driver's side mat.
I ordered a set of Lloyd's Mats which come with the OEM location grommet for the retainer clip. Unfortunately I broke the retainer clip getting the mat out. A quick search on eBay turned up the identical clip: it's Nissan part number 74985-4Z000 . Available from multiple sellers for about $8 shipped.

For future reference the clip has a cut facing towards the rear of the car. To remove a mat, you must first slide the mat back so that the mat's grommet disengages from this cut in the clip's post.

I can confirm that this part is an exact replacement for the Suzuki part.

It's a good cheap thing to replace if yours is broken/missing, bad things could happen if the driver's mat slides forward and interferes with the pedals.
