Side Mount Wheel Well Conversion to Storage Compartment

[Nasukau]

Hi All,
I currently have a 31 coupe with dual side mounts. I am wanting to only have one spare and locating it to a rear mount. I am not going to change my fenders out in case I ever want to revert back. So I was wondering if anyone had turned the side mount wheel well into a small storage compartment with a closed lid. If so could you please post some pictures.

Thanks,
Denny
