Yes Amanda the genuine bmw one does ( so does the pre face-lift) .
If you look at my picture above of the turrets and the brackets you will see the brackets are different.
But you will also see the holes in the turrets at the bottom are in different places there is a 25 mm difference in each side ( the 700 and 750.)
The reason for this is the face lift zed 3 got bigger rear speakers so they tweaked the turrets, brackets and deflector to suit.
@Synclare Adrian , couldn't find one at the time so ended up tweaking a pre face-lift to fit.
Until is got a set of roll bars ( off you as it happened)
.
@Mandyminor
Adrian has the right one for you he is one of our resident forum breakers.
What do already have fitted to your zed .
