16:1 vs. 24:1 steering

I was thinking more about the handling perspective. When I bought the car, it has manual steering with the aluminum steering box, and what I assume is the standard 24:1 steering. It's been apart for a long time now, and I honestly can't remember what the steering was like. Is there any kind of markings that would designate what the steering ratio is?

I was looking at steering boxes from Jegs. They are 16:1, and are $292.00. I thought that was a good price.
