That will be a fun project. I would suggest that "if" you can get it running and driving safely to do that. (Tires, brakes, cooling system ect). When you decide to start tearing it apart, have several sizes of ziplock baggies and some magic markers available. I use "snack size" to 2 gallon baggies. as you remove parts, mark them (on the back side) with your trucks info --- year, make and part ID). Put all the mounting hardware in smaller baggies and attach them to to part they hold on. It is also helpful to clean and paint the parts as they are removed before putting them away until you put the truck back together. I bought a 5 shelf unit and several clear plastic storage boxes. Mark them with the system or area of the truck ( under dash, engine, tail lights, etc.). Put the small parts and hardware in the boxes.
