I ordered the new part and chose standard delivery. The part still arrived the very next day. I'm very satisfied with that. I had to take the stop off of the front of the rack slide and pull the rack slide out far enough to get the adjuster off. Once done, the adjuster wheel will roll out of the front of the slide. The old adjuster was a little different and just clipped onto the rack. Once it's unclipped, just swivel it and it comes off the rack. The new one had a small part that slides down to lock it in place instead of snapping it on the rack. Otherwise, they're nearly identical.
