nice to hear you have the donor. now the disassembly fun starts, lol. it's always good to take pics and notes on how stuff was put together so later you can remember. I know it doesn't take long to take a complete truck apart and box the pieces. if the pieces are labelled or pics taken on how they originally fit together it can really help later. some will even take a pic of what is in each box so they know where the parts are. thumbdrives are cheap.
not trying to say don't do what you want to do. as a firefighter I have been to many collisions where seat belts were not worn. the impact on the rescue crews removing the mangled deceased body parts can be significant and long lasting. maybe you could reconsider the no seat belts thing and possibly install some seats with the belts already integral to the seats if that would make it easier?
