Dear All,
Don't need a response to this as I found Junsei Autoparts in Rochester,Kent on eBay who supply a repair kit with full instructions for £29.00 !!! Mazda wanted £496.00 for new Luggage Cover assembly !!
It was easy to fit and works perfectly !!!
The problem is the plastic bush that fits into the left hand side of the tube that the cover wraps around. A spring inside the tube has a curled bit at the end that fits into a slot in the plastic bush and the slot either wears away or breaks. The replacement part is made of aluminium and should last the lifetime of the car !! You can call Junsei on 01634 650001. They are very helpful.
Regards
