I am trying to repair the lower cab back and corners on a 30/31 Closed Cab.Trouble is...M.I.A...! I have been given the rear subrail crossmember and some tudor 'B' pillars (grafts for the bottom 8" or so) I have witnessed off of the dovetails for lenght. The problem is I have no idea of what the door post to subrail joint looks like??? Anyone out there have any good pics? Thanks guys!
