Thanks for the info but I'm still having problems. There's one nut (which I removed) on a stud at the front of the emblem, but there's some other fixing near the back edge too. It's like there's another stud but I can't see it. The trouble is the back of the emblem is over the front strengthening channel of the hood, so it's barely accessible anyway. With a torch and a mirror between the channel and the underside of the hood I can just about see some slight protrusion but there's nothing to unscrew. The emblem can be wiggled slightly from side to side (so I guess it's not stuck down), but it's too tight to see what's holding it. Any other ideas?
Thanks in advance,
