This is a front wheel bearing kit that gives you bearings for both front wheels, seals, and nuts. Everything you need to replace the front wheel bearings on both sides except for the grease. If you are replacing your front brake rotors, you should also replace your wheel bearings so that everything is new. This early version is supposed to work up to build date 8/1983. You can find this on the sticker on your front driver's side door jamb. However just to be safe you should measure the inner diameter of your outer bearing. If it is 19mm then use this kit. If it is 21mm then use the later version of the kit.
