Replace broken all weather mat fastener

I am trying to find where i can get new fasteners for 2016 all weather mats. One of mine broke and I would like to replace it. I tried a set on Amazon but the interior of the faster was too wide. Thanks.

These are the ones I bought for my Miata years ago, one site says discontinued, but maybe it will give you a start. I will look to see if I have any left over to see if they are the same. Auger Hdwr 1SIDE Kit - Mazda (0000-8B-D01)
