Thank you for your suggestion it was appreciated. The issue however, for me, is that some years ago a boot lid strut failed just at a time when my wife was placing groceries in the boot and the boot lid fell down on her forehead and caused long lasting injury. I have therefore decided to replace the bonnet struts as after being in service for 12 years both are coming to the end of a useful and safe life - I have already bought the new struts but Holden has used a fixing type which I haven't seen before and I was wondering if any member has had the same issue and could advise me what type of socket is required to unscrew the 2 bolts on each fixing plate.
