I take my rear seats in and out a lot, with daily driving and kids then conversion to getting out for trips. While the Grenadier seat hooks are workable, I found the nutsert came loose, and it has become more of a PIA. Ladisalv Cocher created this design that works great. While I was at it I replaced the nutserts with a longer, stronger insert. Ladisalv has created a website to sell his designs. https://askitus.com/
