Adding Power Steering

[belliott77]

Hi All,

I am new to this forum, just purchased a 71 Blazer.

It has manual steering and I am looking to add power steering.
I went to the salvage yard today and didn't find any units
on a 72 or earlier truck, but I did find several on trucks between
74 and early 80's. It looks like these parts are visually very similar, but
they are not the same part numbers.

My question is, does anyone know if they will work? I don't want
to spend the time and the money pulling them if I cannot use them.

Thanks in advance for your help.
