Hi there, anyone know if the instrument cluster for a 1985 300TD wagon (W123) would be the same as 83 f the same model? Im looking to buy a used one off someone but without seeing it I cant tell if it looks the same and would have all the same instrumentation connections.

Im switching the cluster from Miles to a metric cluster as I'm in Canada. I thought I would try and advance the kms to reflect the same milage as is recorded on the original odometer. Is there any simple way of moving numbers up about 100 000 kms? (i.e. hooking up a drill or electric motor to the cable that turns the odometer etc..)
Thanks
