I just installed them. Took me 10 minutes to do both sides. Used my trim tool to take off the plastic trim (prying the bottom seam first and pulling off the rest). The new brackets came with the T-wrench. Super easy. The new brackets are not quite as thick as the stock ones but they feel heavy and robust. The seats latch in perfectly and are perfectly aligned. when I shake the seat backs with my hands after latched, there is very slight give that I can hear because of the brackets being slightly less thick than the factory ones. I'm not concerned about safety, just about possible rattle. If it becomes an issue I'll use the old "wrap with felt tape" fix I've done with my Toyotas in the past (they are notorious for rattling noises in seat latches). I'm very happy with them and when I sit in the back, I seriously feel like I can nap back there vs. the "sitting on the toilet" position from the factory. Highly recommend. I actually ordered from another seller that had it cheaper:
