I got them from one of our forum members, whaleblue22.
They are at 4x4parts.com though.
Yesterday I was going to take pics in the sun, but honestly, they were blinding. I had waxed them right after I put them on.
They were so easy to install, I didn't need instructions. Just laid there for a bit (the instruction/pics whaleblue sent had fallen out of the box during shipping) and looked up. The hangers are very unique. They look sorta like ell's with the short part of the ell being the bolt. You push them up into holes in the frame and the bolt end drops down through an adjacent hole. Pretty slick. You can't go wrong as the front hangers are skinny and the rears are wider and won't go through the front holes and don't match the adjacent hole distance. If you lay down there and hold them up to the holes, it is very apparent how they go on.
Cost? about 300 shipped.
Quality? Polished 2" stainless tube welded to 1/4" stainless plate for the brackets. Perfectly welded. Perfect fit. Great care was taken to weld these things precisely to the correct dimensions in all spatial angles.
