Refurbishing older Alenco Aluminum non-Tilt windows 1/2

Question

Refurbishing some older windows which I believe were made by Alenco in that late 80's or early 90's.

There are three parts that I need to verify part numbers for. The top sash guide should mate with the channel balance, I include both on this query hoping it might help identify the necessary parts.

Part 1 - Channel Balance
1/2" Non-Tilt, has the number 2740 stamped on it.
May be series 351 or 390?

Part 2 - Top Sash Guide
Struggling on this one. It's black, 1 1/4" tall, screw hole is 11/16" from top and centered relative to cap, but the body is offset a bit. Hopefully this is clear in photos.

Part 3 - Sweep Lock
2 1/4" hole spacing. latch is 1/2" from top.
Pretty sure this is part 90-063

Once I confirm the part numbers I will finalize the quantities. Thank you very much for your help!

Thank you for posting. For the balance, check out our Series 390 and see how it compares to what you have. As for the lock, you might want to consider our 90-063.

I'm not so sure about the top sash guide, though. Could you give me more detailed dimensions? Take a look through our Top Sash Guide Section and examine the products we have to get an idea of what dimensions we will need to know.
