Can you put a 1991 Cutlass power steering into a 1991 buick regal?

If they both have the same size engine the pump should be the same. Both cars are built by GM.

If the bolt pattern and pullies are the same and tube connections are the same it should be OK.Can you put a 1991 Cutlass power steering into a 1991 buick regal?what exactly are you talking about? the steering column, the pump, the steering sector? Or just the steering wheel? Lol
