My easy way is to buy a 6 pack of his favorite, and then call my buddy with the longest arms. He can usually reach far enough to hold the nut with a breaker bar while I take it out from the top. Either that, or get it high enough to get under it. Either way, it’s pretty much 2 people. Sometimes you might be able to wedge a wrench on the top and do it alone from underneath. But that’s usually an exercise in frustration for me.

You cut holes for the bolts in carpet before?

I can’t speak for your car back seat, but with the seat cushion out there’s often bolts at the bottom that let the clips at the top slice out.
