Those are the steps that I used today to change my miles/h speedo dial to an european one First, remember: Disconnect Red Power Connector under hood 1. Remove the six screws on steering wheel hub and remove steering wheel. Pull horn button and disconnect wire 2. Place towel over hub to protect it from scratches by dash panel when removed.
5. With your fingers (using your nails) remove the four warning lights in each corner (one at a time) and pull them from the panel. 6. Look in the holes you have just created and remove the four screws. In fact, I only have the two inferior screws. I advise using a magnetized screwdriver.

7. Remove the screw partial odometer unscrewing the metal ring (see picture) Image Unavailable, Please Login
8. Place fingers in two lower holes and using a lifting pulling towards your chest pull out the panel far enough to access and unplug the electrical connector of the speedo. The panel with instruments will now be in your lap and removal of the speedo is two knurled knobs away. Image Unavailable, Please Login Image Unavailable, Please Login
With the speedo in a work table: 10. Remove the chrome ring and the front cover 11. Remove the speedo needle carefully in a vertical direction using your fingers (you can use a curve instrument see image) 12. Remove the two screws next to the speedo axle. Image Unavailable, Please Login
13. Remove the dial face pulling yourself (see picture) 14. Remove two pressure screws by lever at the bottom of the dial as see in the picture Image Unavailable, Please Login Image Unavailable, Please Login
15. Remove the two intermittent and light indicators behind the dial, and move to the new dial. I have taken the opportunity to fix with duct tape and some glue 16. Be carefull to reinstall the speedo needle. It should stand at zero. 17. Go the opposite way to mount Image Unavailable, Please Login
Great thread, thank you! I would love to do this, as my 84 Euro QV is a LHD UK-spec car with a mph speedo, and I would greatly prefer a km/h speedo (Canada has used km/h since the mid-1970s). Now my problem is to find a km/h face for a QV speedo? Where did you get yours?
Hello, I find it in ebay 154USD. Aluminium disc, good quality Ferrari 308 QV 328 Speedometer Disc km/h New. Seller: misterfiat
Yes, It is much easier to read. I have not been able to send more pictures because it seems that my memory is full. If someone wants to know more please send a private
I have some concern with accuracy just changing the face from prior experience on different cars. I have noticed that they also need calibration or they will be quite in accurate. For example, at the 12 o'clock position , is the speed on the new face the same as on the old face (if you do the appropriate conversion) also the max speed indicated, is it the same given the conversion. Looking at the dials in your pics, at 12 o'clock it reads 100mph on the old face but 140 Kph on the new face, which is not the same ...
So then the face is wrong. If the speedometer was correct in mph it will be correct in kph. Only a bad face or a face calibrated for a different speedo will make it "seem" wrong.
I suppose, I just know changing faces often is not accurate from prior experience in other cars/trucks (i've seem some extreme differences in trucks). I don't think it's simple as just the face that's different between kph and mph speedos and i.e. kph speedo face is calibrated for a kph speedo.
How are the odometers different between a mph speedometer and a km/h speedometer? Even if the scales on the two faces are equivalent, the former mph speedometer might show speeds in km/h, but it's odometer will still be counting miles. What needs to be done to convert the odometer from miles to kilometres?
If you look in the old dial that combine both miles and km, you will see that the conversion is made, when the needle pointing 100 miles / h corresponds exactly to 140 km / h
Sorry Albert, I wasn't clear - the odometers are the two sets of rolling numbers that track the distance the car has travelled - primary is the upper odometer, and secondary is the lower trip odometer which can be reset. In your photo, the lower trip odometer shows 811.x miles. Even when you change the face from showing speed in miles per hour to km/h, the odometer which records distance travelled continues to count miles, unless you were able to convert that also?
Change the pick-up/pulse generator on the engine/transmission, passenger side. Easy to reach. But then that might cause the Speedo to not work properly.
Ah, ok that's correct, You have your reason. But my car comes from France and the odometer was in km, first or second owner changed the dial to miles when it was brought to the United States. And I have returned to the original In other car you must to convert also the odometer to km PD sorry: 100 miles/h corresponds to 160 km/h
^ okay it just looks from your photos that at 12 o'clock, it reads 100 mph on the old face but 140kph on the new face. if it was a km speedo originally, probably more accurate now with a km face!
