Part identifier inquiry

Hello!

Thanks for reaching out to us. We don't sell a replacement for this latch and we're not familiar with it, unfortunately. We may be able to help with the balances if you need to replace them. We will just need to see an undamaged balance removed from the window along with any brackets or attachments. 

Looking at your window in the photos, it appears that the balance rod is not centered in the window track like most windows. That could be the reason you have that type of guide in the middle of the track to help guide the window when you open and close it. I could not find that guide through any of our suppliers, unfortunately. I wonder if there is something else that could be used. You say the window makes noise. Possibly you need to spray some lubricant into the track. Or replace the balances in the window. That might help with the noise.

The closest nylon guide I could find is the 15-159 pivot shoe. It is 5/16" wide by 3/4" long and 3/8" high but is still very different so I can't promise it will work for you.
