It is close IMO with just a quick look. It looks very similar to my final install. The only thing you might want to try is pushing the snap up bracket forward as tight as possible and maybe a little more ball tilt. The top coupler designs do not give you quite the clearance as the lower couplers do. I trust you did visit the sticky on WD hitch set up on this forum. It is one of the best there is on the Dual cam set up. Also recheck all of your cam arm bracket measurements before you drill those holes and apply the correct torque to the self threading bolts and ball. A new high quality bit or two and a 1/2" drill motor will make the drilling quicker. Good work so far!
