Steering box

[Macbuick]

Hello,
I hope someone can help me...
I ve the opportunity to buy a steering box, the owner says it comes from a 1982 and younger camaro or firebird.
From left to right it takes 2.25 turns lock to lock, is it really a short ratio?
I would like to put it in my 72 Skylark...is it possible or is there some modifications to do?
Thanks a lot for any help...
i join pictures of it....
