Rear seat attachment? Custom attachment points?

I am trying to plan a custom seating arrangement but I have never see how the rear bench(es) attach to the floor?

Anyone ever make a custom setup?

My plan would be able to move a bench to it faces the side doors for beach days and have a 2 seater L-off that with some space.  Like a living room that can be shifted around.

Can someone take some close ups of the floors and attachment points and post them?

Any good sources for aftermarket benches?  I did find nice 2 seaters for jeeps.

I put a seat in from a 1997 Astro custom. Just through-bolted to the floor with giant washers on the bottom. Used Grade 8 hardware.

Appreciate it. Any special locking hardware to make sure it doesnt vibrate loose over time?

Oh the possibilities....

I made custom brackets (very stout!) for a Ford truck bench seat and just bolted it through floor with large/heavy fendr washers. No worries about it loosening, but do have some lock washers on it. No pics at the moment but I think it can be seen in my project thread.
