My 1990 4x4 Cosworth has a mirror that is approx 200mm across the widest point and has a dip function lever that you actually turn to the left or right. I have attached a picture but it is a bit hard to see. I just received a mirror off a Ghia which is approx 225mm across and the dip lever just toggles forward and back. (other picture) Can someone confirm which type should be on my car as I have always felt the mirror is too small as I can not adjust it so I can see the whole rear window at one time. Thanks David
