For 1969, the dealership worked with Chevrolet to have the L72 engines installed on the factory assembly line using a Central Office Production Order, or COPO. The orders included power
disc brakes, spoilers, cowl-induction hood, a 4.10 Positraction rear end with gears that were heat treated for strength, a bigger front anti-roll bar, and a heavy-duty 4-row radiator. Buyers of the car had the option of either the M-21 four speed or the Turbo Hydramatic 400
automatic transmission. A total of 201 cars were sold in 1969, 171 with four speed transmissions and 30 with automatic transmissions. Yenko rounded out the visual package with special "Yenko 427" badges, stripes down the sides and hood, and the
sYc (Yenko Super Car) on the headrests. According to the Camaro Research Group, standard black interior (code 711) was the only interior ordered by Yenko in 69. ==1981==
