I was able to find parts for an restore the crappy little tach that was put on my 73 Camaro back in the 70's. I have no idea where it came from,but he owner back then had recipts from Motion and other speed shops.
The dashboard is a piece of mirrored acrylic from Motion that was put on the car back in about 1977. he tach is a mystery piece put on probably at the same time. When I found a spare parts tach the seller said it was supposedly removed from a 1968 Berger Camaro. Who knows. I only want to keep it for my own nostalgic reasons.
The way it looked when I bought the car in 1989
