69 Power Steering
All 69's used the same variable ratio power steering gearbox with approximately 2 1/3 turns lock to lock. Z28, L78, and COPO cars had a deep groove pulley on the power steering pump.
- Non-Z28 and non-SS cars with power steering used a 5.25" pitman arm (forging # 3953219) and the longer steering arms (3954873 RH and 3954874 LH).
- Z28, SS, and RPO N44 had a faster overall ratio by using a longer 5.8" pitman arm (forging # 3953227) combined with shorter steering arms (3954875 LH and 3954876 RH).
The 69 idler arm was the same as the 68, 3917581, 5.25" long.
The drag link (a.k.a. center link) for 69 power steering system is 1.125" in diameter, much larger in diameter than the .95" drag link used for manual steering.
