F-41 12:1 close ratio steering box?

Well when I replaced the one in my Hurst, there were three options at AutoZone. And I think mine was 2.5 turns lock to lock also.

Got mine from rockauto.com, same box for Buick GN, Monti Carlo SS etc...
you can also use one from a f body z-28 or formula that had 16 in tires.
