126 Chassis Front Stabilizer Bar Rubber Mounts x 2

I have no specific instructions for replacing those bushings.

They are split so you do not need to completely remove a sway bar in order to install them. You may be able to find some factory specific instructions by doing a deep search on the Internet you will need to disconnect the two ends of the sway bar from the upper control arm and you'll need to remove the brackets so that you can lift up the sway bar enough to get the old bushing out and roll the new bushing in and slide it into place.

If your existing bushings are undamaged and still soft rubber, then you may not need to change them.
