I am looking for four sets of spiral balancers with the appropriate parts to attach to the bottom of the window and slides.

Thanks for posting. For the pivot shoe and pivot bar, see if the 15-015 and 26-040 match up. If the spiral balance is 5/8" in diameter, see if the S600-12 is what you need. Let me know if you have further questions.
