I have recently purchased parts from a 1968 Camaro that is under taking a massive custom build. The gauge cluster has a 160 mph speed-o-meter. The cluster has the turn signal indicator and 2 idoit light in each side of cluster. I can't find any info on a 160 speed-o-meter. The firewall has been covered so trim tag info was unavailable. It appears to be completely original. Info on this would be greatly appreciated.
