A quick learner says:
These pictures are from balancer. Front & rear. Windows purchased approximately 1999 from Home Depot. Thinking it?s a 8500 series ? Could you help me find the replacement part #. Thanks

Hello,

Your photos show our 15-180 pivot shoe, 15-181 coil spring and 15-182 bushings. The coil spring that you'll need is our S190. You'll also need the spring weight number stamped on the spring to choose the correct coil weight. Thank you!
