In his book "On a Clear Day You Can See General Motors" John De Lorean used the '69 Camaro dash cluster as an example of how out of control Chevy had become.
"At one time there were an unbelievable 2,720 possible alternatives for Camaro dashboards."
I have been able to duplicate that number. It may be technically correct but assumed everything was available without exception. For example the COPO 140 mph speedo was n/a with U17 Special Instrumentation. But, there were combos you may never see such as a 140 speedo with U16 and a column-shift TH400. The actual number is probably 1,880.
There were 5 colors, 4 possible speedometers, 4 possible tachometers plus the other options. Give it a shot some cold winter day.
