I dont no if it will work yet but the theory is I have got some uk clocks as a complete and im hoping its just plug and play but will report back once fitted as for the speedo being out take the clocks out take thw front off pull the needle off using said method then on a lonh quiet road using sat nav drive at say 15mph on the sat navthen push the needle on is how im goin to do it then that shoild be it rebuild all back up and check it at other speeds it may not be bang on sat nav speed due to delay and such but a couple of miles an here give ot take should be fine.
