Rancho Front Adjustable Track Bar Jam Nut Wrench Size?

[cavguy]

Does anyone know the size of the jam nut on the Rancho front adjustable track bar for the JL? I need to get a compact end wrench (or crows foot?) to fit this sucker. What size wrench do I need to fit it?

In case anyone is curios, you will need a 1-5/16" compact wrench, or Crowfoot wrench in order to tighten the jam nut on the adjustable track bar.
