Milgard replacement balancer

Based on your photos, you have either our S380-28 or S385-28. The only difference between them is the size of the bottom fitting, which is indicated on their respective store pages. You'll need to measure your bottom fitting to confirm which one is the better match.

Awesome, I'm glad to hear the balances worked!

As for this other part, this is called a top sash guide. I actually don't think your exact model is made anymore, though. I only know that this is an older Milgard type that we haven't been able to get a hold of in a long time.

The closest match we have in our inventory is the 18-009. This may just work for you, but it would require trimming the "edges" off the top part of the guide so that it will fit in your sash. Even then, I highly recommend looking over each dimension we show on the 18-009 store page to confirm that it otherwise lines up with yours. If it differs, let me know how and I can try to find something better.
