How's about these discs......

Someone said that the disc bolt holes are 4 inch pcd, I know that the MG Midget uses wheel stud pattern of 4x4inch pcd so I would need to double check that the brake disc uses the same hole pattern as I could have been given mixed messages over this, unless anyone here knows what they are?
Plus they are cheap and easy to get hold of.
