I'm selling my '79 mustang speedometer, original in the box. This speedometer has KM on the outside, and MPH on the inside (unlike most other speedometers). I've had this speedometer since I purchased my 79 mustang, and only swapped it out after 51 miles (since I started driving it in the United States). This speedometer has been in storage since then, and is in excellent condition.
I've attached a link to my eBay auction, but please don't hesitate to contact me with any questions.
