Make your own. Its a basic 1" steel tube, threaded at the top for a fancy cap, and maybe a small horizontal groove cut the clear the lower pinch bolt. Originals were hard chromed. If tube is hard to source a solid bar would do, and while waiting for Drags at least you can get it mobile and have the satisfaction of some progress. Service Sheet 213 has the details, use threaded bar, nuts, and a couple of sheet metal plates in lieu of the official assembly tool. If you have the parts but they are worn, the column can also be rotated to present a less worn area to the load side of the bushes. The sliding carriers can also be swapped side to side and top to bottom so that the least worn areas of the bushes take the load on the columns. New bushes and columns if you can get them, but short term rearranging the bits will be of some benefit.
