Hi Mark,
Sold my zed a couple of years ago, have just been clearing out shed and came across my boofsquire rack (imported from US).
Not sure if you are still interested/need it.
I used it for transporting windsurfing gear/ surf boards/ bikes, never had any problems with it and once you have the knack it goes on in a few minutes.
anyway if interested let me know?
cheers
Ade
