2023 Taco AC Back Seat & Headrest Removal

Greetings!
Does anyone have any helpful hints for removing the back seat bottoms and headrests in a 2023 Tacoma Access Cab? Apparently, the 2023 back seats are bolted on slightly differently than the '21 or earlier model years.

BACKGROUND: I just bought a new 2023 Tacoma AC (did not want the turbo engine in the '24s). My '17 Taco was a fleet model AC without back seats, and my '05 had the fold down bench. I love my new Taco, but these useless back seats in the '23 are diminishing my cargo space for roadtrips! And don't get me started on those back headrests. (We don't have kids, and no adults could fit back there). I want the seat bottoms and headrests GONE! Would like to keep the upright back seat panel intact and unscathed, but I understand that has to come off temporarily to remove the headrests. (And I don't want to use the SawsAll that close to the rear window! LOL). I looked through other forum threads on back seat removal, but don't see anything specifically about the 2023 model year.

Toyota LockTited the bolts, so my husband and I gave up and are going to see our buddy who owns a body shop and his impact wrench next week for assistance. So.... I'm looking for any intel that will make the seat bottom and headrest removal go more smoothly.
Thanks, y'all!
