The Base instrument cluster is supposed to have a trip odometer (per the manual). A buddy of mine just got a Mustang with the base cluster, but we can't find the reset button. His is blank (the right 3 buttons off the cluster).

Are we blind?

 

press the button in the speedo and it changes to the trip counter. hold it down till it beeps while on the trip display and it restets.

 

Thanks, Tbird!
