If you go to addco.net you can get a list of dealers. It's the 737 that fits our trucks. Todd Z had posted a link a while ago, I will see if I can find that one.( edit. . . www.neverenoughauto.com ) I paid $173.00, including shipping. The kit comes with new end links, so if you have the OEM links this is an upgrade. I had the Moog upgraded links and just kept them. Just get some grease to lube the bushings so they don't squeek in the future.
The issue with the brackets. The bar is thicker, along with a bushing makes the bracket wider, meaning the spacing from one hole to the other is at least 3/4 inches too wide. You have to bend the bracket together and force it to fit. You also have to drill the holes larger because the OEM bolts don't fit the holes. Once you get both bolts started and straight, you can then tighten them snug. It works fine.
