UP FOR YOUR CONSIDERATION IS ONE USA MADE NOS DATCON PART # 71927-03  MODEL # 30LP18EM  0-80 MPH 0-130KMH SPEDOMETER AND ODEMETER. THIS IS FOR USE IN EITHER GAS OR DIESEL APPLICATIONS (THIS REQUIRES A SENDING UNIT AVAILABLE AT A DATCON DEALER). THIS FITS A STANDARD 3 3/8" / 86 MM OPENING. MOUNTING BRACKETS AND HARDWARE ARE INCLUDED. IT DOES NOT COME WITH THE LIGHT SOCKET , BUT A STANDARD GM PLUG WILL WORK.  THIS WORKS ON 4, 6 , AND 8 CYLINDER MOTORS. THE PURCHASER IS RESPONSIBLE FOR THE APPLICATION, YOU MAY BE ABLE TO CONTACT DATCON FOR FURTHER INFORMATION. THE RPM NEEDLE RESETS UPON APPLICATION OF POWER. THE BOX IS WORN FROM STORAGE , BUT THE GAUGE IS BRAND NEW. I HAVE SOLD SEVERAL OF THESE LOCALLY WITH GREAT RESULTS.  I FOUND THIS SAME UNIT ON THE WEB FOR OVER $400 US. The original box is beat up, but the Speedometer is in nos shape.
