well, I got it done. came out really nice if I do say so myself. 
I decided not to cut holes at the spare tire nor up front. The front half of he lower part is secured to the "lid" and the right side is removable to gain access to an amp I have bolted down there. The amp in the pic is now gone, made way for a larger one. Works great and it fit perfectly.
