Power steering or manual steering

[bradford]

I need some help, I am going to get a power steering colum off this guy for my 73 duster.Its a 4 speed steering colum cause I switched over from a auto to a 4 speed.But I was woundering how you tell the difference between a power steering colum and a manual steering colum?Any help would be great.Thanks

the shaft on the column (the underhood part) will have different lengths depending on power or manual steering.

The steering coupler diameter that attaches to the steering box is larger in diameter. The difference in shaft length should be obvious.
