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

At a car show (Cars & Coffee type) at Gateway Classics in Denver area, I saw this '67 Barracuda Convertible with a 6.4L Hemi and 8 speed automatic. Beautiful car, but this instrument selection is something that I never saw before. Can anyone identify the source of these gauges. The speedometer is combined with the tachometer in the left gauge and the right cluster looks aftermarket but tastefully done. But I have no idea where these gauges came from and have never seen this setup previously. Be very interested to know more about them. I have my '68 FB FS nearly complete, so I won't go this way, but others may be interested.
