Here is what I have in my notes:
SWAY BARS: Front Bars: ALL '70-'81 T/As & Y96/Y99 equipped Formulas came with 1-1/4" (1.25) front sway bars. Std. Formulas had 1-1/8" (1.125) bars. Std. Birds had 15/16" (.938) till 1975, then it increased to 1" Rear Bar: 1970-72 T/A & Y96/Y99 Birds = 7/8" (.875) 1973-77 T/A & Y96/Y99 Birds = 13/16" (.813) 1978-81 T/A & Y96/Y99 Birds = 5/8" (.625) 1978-81 WS6/WS7 equipped = 3/4" (.750)  Not for sure on the lack of the bigger bar in 1970. Don't remember a bulletin on it?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
