Control arm swap

You are right, that part is not listed on my regular sources. They do have the bushings listed that you can replace if that is all that is wrong. Ball joints are available separately too.

If the arm is bent or badly rusted, visit any salvage yard and they will have a "Hollander" interchange guide for this purpose. It lists every part for your car model and year with a code number. You look that number up in the back of the book, and it will list every model and year that used the same part.
