thunderbird steering box

Several years ago I bought a steering box at a junk yard. It came off a 75 or 76 T-bird.The turns lock to lock were 3.5 turns.The regular Ford box is 4.1 turns. Unfortunately the tag had been bent off.I installed this on a old torino of mine and it had tighter feel.Does anyone know any info on this steering box. I think the gear ratio must be 16 to 1.The info that I am looking for is the tag number from Ford.Two if it was a Ford option.Three where to get another one. Believe me your torino base body car or full size Ford from 65 to 78 will respond better when you are driving around. P.S. the one I have is not for sale.
