MANUAL STEERING FOR DAILY DRIVER

How do you determine what the ratio is? Is it printed on the box? Mine takes so many turns I was thinking about adding a suicide ball to the steering wheel.
I believe a 24:1 box is 3 1/2 turns
16:1 2/ 1/2 turns
Don't know about 20:1

16:1 manual box may present parking difficulties

16:1 box solved the steering/ headers clearance problem on my Dart with Doug's D453 headers
