Replacement parts for window coil housing and balance

A quick learner says:

I purchased these Parts back in 2014. My window keeps getting stuck down at the bottom. They are pulled down Windows so if I bypass that bottom part I can slide the window up. But once I close it, it gets stuck again. I tried to send a picture of my order from 2014, which I kept a copy of. 

I tried to locate the pots but it looks like some of the numbers may have changed. The following is a list of what I had ordered before and hopefully you can locate the part numbers for me. 

The following parts are 16-024 mounting bracket, 15-087 Coral housing pivot, S180-6 6 lb series 180 coil balance, 33-072 screws that were too short. I had ordered two of each. 

Your help is greatly appreciated. I did try to upload from my phone my old order but it wouldn't send my picture. Thank you Pam

Hello, Pam. I'm sorry to hear you're having trouble. We still have access to your old thread from 2014, and reviewing your photos here I still think the products that you purchased are the right parts for the job. I'm not sure why they might be sticking but I'll do my best to help.

Let's try to narrow things down a little more first. Is this a recent issue or has this been happening since you purchased them? Does the window operate normally other than getting stuck at the bottom? What I mean by that is, does it drag, hang up, or otherwise move poorly other than that one issue?
