rear springs '80 K20

[dalea]

I have a 80 K20 3/4 ton 350,thm400, and 14 bolt f/f rear end.   The pass side rear spring 8 leaf is collapsing so I need to replace it. I have come upon a set of 8 leaf springs from a 82 C20 3/4 ton 2wd pickup. The dimensions all are the same, so would these springs work and maintain the same ride height?

If they are dimensionally the same but in better shape it should be the same if not just a little bit higher ride.
