Every single "gun safe" I see doesnt really do what I want and where it goes doesnt work.

I have an 04 crown vic and the safes I see take up the entire bottom or at the top of the tank where the spare tire goes.

Is there some kind of vertical option that rises upward instead of lying flat on its back like a cheap hooker? Im trying to keep as much space as possible and moving the tire to the floor is no option nor is a flat tray taking up the entire bottom of the floor like 90s camerio sub boxes.

I thought about cable locking a air travel safe gun case to the body of the car.
