I have searched and searched but I can't find it. Someone posted up a link to an ebay seller who has the correct allen screws for our bodywork. Fitting my new battery I have dropped 3 of them and try as I might I can't find them amongst the gravel, so I am just going to order a pack of 10, if I can find the things again... can anyone help me with what they are called and the size please? I know different 'bolts' have got different correct names for their slight differences. To me they are just 'bolts'.
