5th gen limited 2500 mega cab interior swap into 2008 ram 2500 mega cab

Looking to start building my 2008 dodge ram into a show truck. Would the parts(seats, console, dash, etc) bolt up exactly? Also on a scale of 1-10 how hard would the electrical side of it be?

If you tear out everything, then yes the dash should bolt in.
On a scale of 1-10, 12. Seats are relatively easy. Everything in the dash is designed to work with CAN bus that's two to three generations beyond yours.
