If yours is as rusty as the bottom one, I'd get another one. At the least, you must sand off all that rust. Inspect the whole length of the rod for nicks or corrosion that could tear up the bushing on installation.
Do not unbend the clip. It's supposed to be tight. Take the clip and put it around the bushing. It goes between the narrow deep groove for the hanger, and the flange that is at the forward end of the bushing.
Install the bushing in the bracket with the gap facing the left side of the tunnel. Put some grease in the ID of the bushing.
Grease up the entire length of the shift rod. Insert it from the front. If you have a helper, get them to guide the tail end of the shift rod into the bushing while you push it in from the front. Initially it will take a fair amount of force to get the wire clip to expand enough to allow the shift rod to go through. I used a wood broom handle through all the holes up front to push on the shift rod once the tail was aimed right. Once you get it started, you're home free. From then, all you need to worry about is making sure it clears all the tubes in the tunnel. When it's in it's final location, make sure there's plenty of grease in and around it.
