Cheers dudes for the help,
just been out to look at the rears, and i can see that the stalks are groved so the nut can screw on to it, the ones i got are smooth so nothing for the bolt to screw down on...............................
theres is however at the bottom of the grill a little hole that the spare part guy said I need to put a screw through to attach the grill to the door, cant see that hole on yours Diz?
