Good question. My car was built for use in Thailand so it is right hand drive but with the speedometer only in kilometers. The donor car I am using to rebuild mine post flood is from Japan, so also right hand drive and would normally be kilometers I'm sure but this car was specified to have miles as well. Maybe it was originally a UK model or intended for UK. Not sure who other than UK uses RHD and mph. I may take the overlay that shows the speedometer in km and use it on the panel from the donor car but the legend above the odometer reads km whereas the actual odometer is set to miles.
