Hi grimley. Sorry, I almost forgot to take those pictures, but here they are - finally. Hope I'm not too late and that they are of some help.

thanks duncan, appreciate it.
ill have another look at mine, i can feel where the screws have to go. however the one ive tried (even peeled the headliner back to have a look) didnt have anything to screw into, just a big hole.
Maybe it was just the one hole thats missing so ill try another, thanks again!
