Even easier solusion would be to make a bush that has an id the same as the od of the 16mm ball nut and od the same as the ID of the SMA20.
Then there is enough ali on the SMA20 to drill and tap for the ball nut flange.

I had some made that were the same as the SMA20 and size wise it worked very well, but making it was too expensive and now i get them from China allready made.
