Cut it where you find is best, I cut mine on the bottom flat section, it is not solid. Cut the trackbar to length and then find a bolt or some other solid tube that fits snug to slide inside the cut end of the track bar. 2 inch's in length for the bolt or solid stock would be good. Grind the cut ends of the track bar at a 45 degree angle, slide the bolt inside one end halfway, then slide the other side over the bolt, position everything the way you want it and weld it up.
