thanks cornish 4 . Hello Lobster , regarding clio seat , it doesnt line up at all and needs a certain amount of packing to level , if you are tall ish then you will probably need to take off the runners too . quickest way i found was to mount the seat on an oversize plate , position to suit , clamp , drill and bolt back through original mounting holes . in hindsight probably better off buying a cushion but new seat very comfortable and cheaper than a trip to the chiropractor .
