Thanks, ratherbeflyen.
The newer ones, last 4ish years, Cessna started offering the 172’s with a single rear observation seat instead of the standard 2 seat bench.
I believe that plane is a 2016.
Got just about all the electrical wires and equipment transferred to the new tank today. Just need to buy Velcro stickers.. I have some, that I found a few days ago, and have since lost! Irritating. Lol
I spent a few hours, like 3, organizing and strategically routing all the power cords this evening.
Also stuck the light on top for fun!
Side view - you can see the added dimension I tried creating with the rock work.
