Back to the original question, the "WS6" option first appeared in 1969 as an "power assist group package." The next record I could find was 1978, when it became "Trans Am Special Performance Package" with a larger rear sway bar, 15 x 8 "snowflake" wheels and 225/70/15 raised wheel letter tires. 1982 was the first year I found with record stating the WS6 package included 4-wheel power disc brakes, 15 x 7" aluminum wheels with Goodyear GT tires, limited slip rearend, special steering, firmer shocks and springs, and larger front/rear sway bars.
