Field approval, an IA friend handled that for me.
A nutplate in the aft doorpost is required, the seat bolts to that and to the nutplate used for the stock bench seat side attach.
You also need seatbelt attach points.
I used the nutplate in the floor for the stock bench seat aft attach for the inboard belt attach,
and for the outboard attach I installed a brownline type cargo ring pad.
If I was to do it over again, I would use the (Cessna) parts called out in the BAS jumpseat install instructions for the outboard attaches.
They're tabs that rivet in between a bulkhead & the skin (see below).

Its also a bit Rube Goldbergy as to how its installed and then stowed. For my money, it would be either a stock Cessna seaplane jumpseat or Atlee. Seat installs are fairly serious, so be careful about backyard engineering. Best bet is to follow STC installs or Clyde's drawings.

I have installed several Atlee jumps and they are solid. If you want utility, nothing beats the Dodge. If you want comfort for your pax, keep the stock Cessna bench.
