Joe - Hope your 4th of July is GREAT too! Let us know how the effort pans out.

PS - You ought to be able to grasp the head of that pin on the left (more exposed side as viewed in your video) with a pair of pliers and attempt to rotate it in the yoke. If it doesn't move, give it a dose of penetrating oil like PB Blaster to soak and work on loosening the pin while you enjoy your 4th.
