1969 Camaro Pitman Arm Length
 

Both of these power steering pitman arms are NOS GM.

They can be found in the parts book in Group 6.859

The hole with the spline is 1 1/8"

The short arm is cast 3953219. It is not used with fast ratio. Appears to be 5 1/4" center to center

The long arm is cast 3953227. It is used with fast ratio. Appears to be 5 3/4" center to center.

Thanks Warren for the great examples. Visual aids are so important. Especially since a good deal of the photos went away with photobucket.

Per CRG : “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).

Note that the same pitman arm forgings were used for both manual and power steering, but the splined holes for the attachment to the steering box were different sizes.”
