As I stated elsewhere on this forum I have had problems with the tailpiece above the number plate. It is held on with 2 (fragile) hooks on each side, one slide-in tongue, and a small push pin underneath on each side - all of which have proved to be not up to the job as losing this piece is a fairly common complaint. Two of the hooks on one side of my tailpiece had broken off necessitating making new ones out of Perspex and fitting them using a white plastic mix. I also added the plastic mix to strengthen the other vulnerable fixings while I was about it. I also drilled a small hole in the bottom centre of the piece and fitted a small screw to attach a tether( the red wire) from there to the left-hand rear-light screw (the left-hand light screw is best because should the tailpiece come loose it will dangle to the left, away from the hot exhaust) I increased the size of the holes for the two underneath pushpins to 8mm and fitted suitable larger pins. I hope the pix is clear enough.
