If anyone is wondering, I took a chance purchase used rubber floor mats from a 2014 and Lexus GS 350. So to say it fit well, the only things is the rear has two holes in mats . Where the carpet mats has a single fastener. But all else appear normal.
When Toyota had that big fiasco with gas pedals, they determined it was mats not fastened correctly, AND people stacked mats on top of mats on top of mats. One winter I was working at a Toyota dealer, and I was talking to a customer in the service drive and he was showing me his car, he had 5 mats stacked on top of each other on the drivers side. Basically he'd get one dirty AF then buy another set and just put it on top of the old one. Granted this is a highly unusual circumstance, but, even 2 mats is too much. I would remove the carpet mats and at the very least mount some velcro on the underside of the mat and maybe the carpet side so it doesn't shift around
Vooduguru is correct, the pre-floor mat interference style mats had a simple hook
that snapped into a hard grommet in the carpet. The improved design mat shown
in your photos is designed to be held by a bayonet type toggle that turns 90 degrees.
