Re: copo axle codes
On page 58 of Jerry's book he states " the lowest RPO rear axle available was 4.10. A 4.56 or 4.88 ring and pinion had to be dealer installed. However, factory installed 4.56 and 4.88 ratios were available through COPO ordering info. COPO/9511DT is a 1969 Camaro with 4.56 rear axle ratio"
This agrees with the 1969 Camaro Power Teams chart which was used when ordering a car. The 1969 Power Teams show 4.10 as the highest ratio. The 1968 Power Teams chart goes up to a 4.88 ratio.
