Not that it helps you or that you can find them, but I have a 4 bolt steering box in my 1600 that is just over 2 turns lock to lock. I know of 3 of thee in existence and believe they were from early Datrally or Nismo parts that were once available.
The 2.7 Nismo boxes (4 bolt) were works stanza units.
I had 2 back in the day. Sold one locally & the other went with the car.
