Metric-Imperial Conversion
Sometimes on eBay Australia you can get the vintage conversion stickers.
OR
print this on plain paper at 125%, for a test fit. If you like it, print on sticker stock then apply to the speedometer
OR
Take the face plate and scan it on the flatbad scanner, then modify it. Finally, print a new one out with the photo printer. You can modify the font, colors, etc. You might think you can simply bolt it to the speedo using the standard screws, but it will not lay flat. Adhesive paper (sticker paper) will work
Speedometer Calibration
It is normal for the speedometer to read fast. The specified tolerance is +5% -10%. So at actual 60mph it can read 57 to 66 and still be acceptable. But you can blueprint the speedometer to be closer to the actual speed.
Speed Buzzer
Starting in 1972, all JDM speedometer came with speed switch for warning of excess velocity.
Amplifier Speed Switch
1972 Japan, Australia late utes and 1973 USA used a speed switch.

Custom Faces
Z Speedometer
280Z speedometer fits in the 1200 dash cluster.
- Swap the mounting cups as the 280Z unit is deeper
- Drill a hole for the trip meter shaft through the back
- The face is to large for the opening in the 1200 housing, so carefully reduce the diameter by 1/8 inch
350Z speedometer looks a similar size.
Electronic Speedometer
Yes, you can fit an electronic speedometer into a 1200.
