Here are some pictures of the bar itself. Taking GOOD pictures of a black part is hard, haha.
You'll notice the bar goes through the end pieces and is welded on both sides. This was the last design tweak to strengthen the welded joint. On my prototype, the bar just butts up to the end piece and is welded only on that one side.
The ends get plastic push in caps to keep junk out.
Here is the hardware it'll come with. I went with allen cap screws since clearance is tight on the front bolt, and getting a wrench in there is a pain in the butt. You will need an 8mm allen wrench for these bolts.
The full kit.
