Steering box question

So I ran across a deal on an '84 Monte Carlo SS steering box. I went ahead and bought it, knowing that I have to change the hoses on the car to match the later style. It is from a true SS car, and it is the 12:1 box. I'm kind of tired of the variable ratio box, back in the day I was used to it, but switching back and forth between the two cars now, makes me drive the '77 like I'm drunk.

My question is this, is it a good box to swap in?

I installed a new 12.7:1 670 steering box from Lee in California and it's awesome. I can't praise it enough!

I picked up this box for 40 bucks.

I'm thinking about doing the Astro steering shaft mod to it.

A buddy of mine did it to his '84 Monte SS and it makes it feel very good.

I'll probably do this mod as well since I have to take the valve out.
