Steering box interchange

54coupe

I have a 1940 Hudson Super six. The steering box has quite a bit of free play. I  have a '42 Commodore box, column, and pitman arm in my spare parts. Can anyone tell me for sure if they're interchangeable? All the rest of the steering components are tight.

41-7 will interchange. The 1940 won't according to the Hudson interchange book.
