Yes, there were 2 versions: long (3954873 RH and 3954874 LH) and short (3954875 LH and 3954876 RH). Good luck on the hunt!

69 Manual Steering
69 manual steering boxes used an aluminum cover.
Most 69's used the same manual steering gear. Changes to the steering linkage were used to change the overall steering ratio. Regular cars were equipped with a shorter 5.25" pitman arm (forging # 3953219) and longer steering arms (3954873 RH and 3954874 LH). Z28 and RPO N44 (special steering) cars utilized a longer pitman arm (forging # 3953227, 5.8" center-center) and shorter steering arms.
A special fast-ratio manual steering gear was used for Z28's with RPO N44. The manual Z28 with N44 used with the same longer pitman arm and shorter steering arm combination as listed above. Z28's with N44 are very uncommon (and not fun to drive).
69 Power Steering
All 69's used the same variable ratio power steering gearbox with approximately 2 1/3 turns lock to lock. Non-Z28 and non-SS cars with power steering used a 5.25" pitman arm (forging # 3953219) and longer steering arms. 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). Z28, L78, and COPO cars had a deep groove pulley on the power steering pump.
