Hi does this trailing arm come with an extra bushing for the wheel carrier end? Also your video shows a solid bushing in the arm. But the item photo, you can see voids, would this happen to be just an old photo of the product? Thank you

The trailing arm does not come with the carrier end bushing. As for the style of bushing it could just be a difference in manufacturers, but should not affect fit and function. You may get one that looks more like the website image or the one in the video.
