68 BB Camaro with 140 Speedo, Yenko Hood on Ebay

[Jeff H]

Does anyone know when the COPO option first became available in 68? Because that would be the only way to get the 140 speedo I assume. Now if this particular car is a color that was discontinued before the end of production and the COPO option didn't show up until the later stages of 68 then is there really an overlap where you could get a Grott Blue car with the COPO option? It just seems odd that Don would have ordered an RS/SS houndstooth COPO car without someone specifically requesting it.
