There is window overload for a car the size of the Centurion in my opinion.

I will use scoops for not only the cabin venting but also the AC rear hatch venting. The Roof hatch vent will be from a Camaro SS Hood flipped so that it works as an exhaust rather than a scoop. This will be positioned toward the rear window break and the roof in a way that is streamlined so it smoothly transitions without bulging like in a hood scoop. There are two different sizes for the Camaro SS hood scoop. The mini size scoop is what I will be using and it is 30" long and 18" wide. This is big enough to properly vent the AC and fill in the rear hatch window void. I will be using an Kubota Orange decal like the decals used in the second and third pictures. The base color of the car will be black with Kubota Orange and white for details.

The side vents will help to vent the interior cabin space which is also needed. I am not set on which ones I will be using for this just yet as they do not need to be all that big. So still searching for these at the moment.

So that is the plan so far to deal with the air conditioner exhaust heat

Some time ago I was playing around with reversing a scoop as a vent. It was mounted on the surface (not recessed as you will likely do). I really didn't have good luck in the proof-of-concept with this particular trial.

I think you may have better luck with the way you are proposing to use the Camaro type.
