I misread the '69 Camaro order form. You are right Stan. There appears to be four selections under the "AXLE, REAR" heading. RPO's G80, ZQ8, ZQ9 and the fourth box is the blank space to write in a ratio. Then the power team chart has four columes Std, Econ, Perf, and Spec. My question is if you could have writen in "4:11" on the Corvette order blank for a TH400 L71/L89 or L88 or ZL1 would it be factory installed or dealer installed? I do not have a power team chart for the 1969 Corvette. The 1969 Camaro Power Team Chart goes up to 4:10 and the '68 and '67 goes up to 4:88. One book lists a 1969 Camaro COPO #9511 code DT 4:56 rear.
Maybe the '68 Chevelle Charley had was ordered by writing in the ratio. Yes Charley that 68 Chevelle would have been a "Contenddaa"
