Well then, I think it can definitely be done. You just need to really plan and measure. It would be cool if you could find some sort of plastic trim that you could use over the edges where you cut, to give it a nice finished look.

Yeah I would probly try and find an extra set of interior pieces just in case. I know it could come out nice if done right. I dont think I will put my spare in there after looking at the size Kenny's took up. Maybe a 6 or 8 inch height would be enough.
