Have received the front C6 Z51 sways on E-bay, and ordered the rears from a GM parts dealer. Does anyone know where I can order online the 2013 updated metal end links at a decent price and receive them relatively quickly. I had ordered the rear C6 Z51 bar from a GM parts dealer in Ottawa, through Jim Tubman. And the communication is terrible. Seems I can only text them if I want information on my order, that has been close to 2 weeks now. I called GM dealer parts departments around my area, and the price per end link was about $90.00 each. Where as if I order them on line I would save quite a bit. Don't quite understand that
