As above its called a bonnet hinge bush... Eer Harry.... http://www.landyzone.co.uk/lz/f7/part-numbers-paint-colours-138302.html make sure you have the 2 round buffers that press into the bulkhead on the same line as the bonnet hinges... water gets in and they stop the bonnet from coming off unless lifted to 90 degrees.
Just done mine
Thanks all i shall get some of those buffers at the same time and probably silicone them in...and maybe some bulkhead seals as that could explain why my ciggys get wet in the dashboard:doh:
