Hi Mike, Thanks for taking the time to reply. It went in the post to you about 2 hours ago . I didn't mark it for your attention this time! You should get it Monday. Aren't they a pig getting the shear screw out? I had to use a carbide burr in the Dremel to get a centre dot and then a TiN plate drill to put a hole in it and then used a Bluepoint Grabit screw remover in the hole, what a palaver, about 1/2 an hour I suppose. Then you can't change the screw so I'll have to put it in the way it came out .
