Spray all the bolts with some inox, then undo all 6 hold down bolts, undo the 3 screws under the fuel filler door and pull the filler free, undo all the wiring, remove the rear step (if you like). I cut the plugs off my old lights from the tub and fitted them to my new lights, the ones on the tray then just lift they tray on and move the rails around until they line up with your holes.
For the fuel filler i just got some 3mm ally plate and made a bracket up, i can get a pic if you like. And just secure your mudflaps in an appropriate spot, i tucked the front ones behind the side steps so they can only rub on the step and not the body.
The tub can be lifted by 2 people although 3 might make it easier. Pretty easy job took me about 4 hours and that was going slow and i had to make a hold down bracket for mine as it only came with one for the tray.
