New rallye dash replacement gauges/tachs (some insider news from the supplier)

I always thought it was just the '67 tach face that was different from the '68-up version along with the angle of the numbers on the speedo.
I can’t speak to the accuracy of what the tech was saying about the tach faces. I thought the 0-6k thing didn’t sound right. In any event, if they are going to go to the trouble of improving them, hopefully they’ll do the due diligence to know what is accurate historically.
