Steering pitman arm

[1967 Impala]

I posted in the want adds that I am looking for a standard steer pitman arm for a 66 BelAir, I guess What I really need to know is .........are the power steer and manual steer pitman arms different or can I use the power one I have ?

Thanks

I believe the power steering one is a different length & jog as compared to the manual arm,do to the position of that steering box mounted on the frame.

The power steering arms have a larger hole in the big end too cause the output shaft is larger on the p/s box than on the manual box.
