it's no biggy, but the order matters or you will get mad
secure car with both front and back wheels out, loose the old screws, let back go first, let gravity work for you as you work toward front of the car
you have like 4 or 5 screws to remove, and 2 bolts, one 13 mm bolt just after the wheel and one behind front wheel near triangle. One you have them all loose just pull hard on nipple so it goes thru the grommet. Same for the small one going around coil.
To install new ones, it's the reverse except i'd do the following: go to the wheel back, put a screw and suspend the line a wire, let like 10cm play, so it hangs.
then go front and push nipple in, place the screw next to the triangle, but do not tightened it, then the first where it goes under car. Go then to wire and reduce distance to small one. you should then be able place back all screws. I'd use new ones for the metal screws, bolts are quality ones and can be brushed. Mine were in very good shape.
Another nice day under the car in perspective
