These are good large mirrors Daz:

Mine passed with these on and Mark's have just passed to, only thing to watch for is that you mount them high enough on the scuttle so that they see over the rear arches. Otherwise, if they are too low, the arches will obstruct a crucial part of the viewing area - same for all mirrors though.
