Quick Steering box ID

I got a quick ratio box out of a '67-'69 Formula S in a junk yard. I had heard about the quick ratio being an option, so I just spun the steering wheel. Counted 3-1/2 turns lock to lock--same as power steering. Regular boxes are 5-1/4 turns lock to lock, so probably the easiest way to check is to just count the turns, as said earlier.
