Cowl water leak?

Is this where the infamous cowl water leak tends to show on the floor mats? I have a couple spots on driver's side a few inches back also but that could be from a foot. Nobody sat in pass side for quite some time. Rained all day yesterday.

 

Get a picture, from the bottom up, of where the water is coming from. It's easier to tell knowing where the water is coming from, as opposed to where the water ends up.

 

yes, passenger floor mat forwardish below glove box.

 

Yes. Look at the video embedded at the bottom of my 1st post here: https://www.tundras.com/threads/definitive-cab-area-rain-water-leak-thread.70464/

If you go to 4m30s mark of that video, you should see the water coming in, and the 3m50 mark shows the exact fastener you need to replace.
