ST-2731 is a special arm used to template the 4040EDA and a GJ 90 series (1-4). There is a "list" add-on price for this special template.
With a GJ90 and a coordinator, you could combine ST-2731, and ST-1754, but it would be better to eliminate the Glynn Johnson, and use a LCN CUSH arm with the coordinator and ST-2648. This is a much simpler, and less cluttered application.
