Based on my experience, here is a list:
air filter
fuel filter
oil filter
transmission filter
half shaft boots (both ends)
spare headlights
spare turn signal lamps
oil seals for the wheels
drive shaft U joints
Glow plugs and glow plug controller
electronic control box (brain)
signal flasher unit ( it is under the dash near the brain)
windshield wiper blades
O rings for the tires (they seal the 2 piece rim)
Manuals! -20P,- 34P ,-20 and -34 repair and the -10 operators.
I would look into changing the lights over to LED type for their enhanced brightness.
this is a start, others can chime in and add the things I dod not consider.
