For 1969, the dealership worked with Chevrolet to have the L-72 engines installed on the factory assembly line using a Central Office Production Order, or COPO. The orders included power disc brakes, a 4.10 Positraction rear end with heat treated axle shafts, (to avoid breakage), a Z-28 front anti-sway bar, and a heavy-duty 4-core 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 front and rear spoilers, a cowl-induction hood, special "Yenko 427" badges, twin stripes down the flanks and hood, (not with all cars however), and the sYc (Yenko Super Car) badge, (again, not with all cars). According to the Camaro Research Group, standard black interior (code 711) was the only interior ordered by Yenko.
