These are what I have, I actually just put them in a few days ago. Nice product and he sells some that have a ring incorporated as well for tie downs; took about 3 weeks for them to show up from Australia. I probably won't ever use the tie downs, I just wanted a way to plug up the hole before I put drawers in so nothing falls in there and rattles around. You'll also notice the large holes in the carpet which you might want to plug up as well. I have a spare workout mat laying around I think I'm going cut a few pieces to "plug up" the holes in the floor as well
They are great indeed! Which back seat cover and mat system are you running?
