Drag link

I am looking at replacing the ball joints on my drag link.
The parts system I have shows a steering box with a drop arm. Connected to this with a ball joint it shows an offset section which screws into the draglink tube.
When i google the part number for the offset, it comes up with a screw in balljoint with no offset.
The one the car is a drag link tube with no offset and 2 screw in ball joints, 1LH thread and 1RH thread.
Anyone know what it should be like?
Thanks

theres 2 types depending on age ,later has tube with 2 track rod ends the earlier has tube with 1 track rod end
