there are four bolts that hold the tail on.
the tail comes off in two pieces.. there are maybe five smaller screws that you have to undo to pull half the plastic tail off that covers the other two bolts that screw the tail on.
Two of the screws are up where you would think the remaining two bolts should be, then there are two more farther towards the rear of the tail, near where the blinkers attach, then one that is in center in a hole that points to the front. (I am spouting all this from memory so my screw count may be off.. there may be a couple more or a couple less, but they are there)
once you have all the screws off you can pop the lower plastic piece off and then undo the remaining two bolts.
unplug all the tail equipment
the right blinker has a D as part of the label (this is Destra, which is 'right' in italian) and the left blinker has an S as part of the label (Sinistra is left in italian).. I tell you this so you can unplug the blinkers and still know which plug went to which side.
