Refurbishing older Alenco Aluminum non-Tilt windows 1/2

A quick learner from Aurora, Colorado says:
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.

Tom,
Thanks for looking in to this, I have attached a sketch with additional dimensions for the Top Sash Guide. I went through your online catalog and could not find anything with the screw hole 11/16" from the top (one of the key features).

Thanks! Hope you can help.

Well, we've been looking around for a good replacement, but we weren't able to find anything exact. The best match we could come up with was our 18-009. Its dimensions are pretty similar to yours, with the exception of the cap, which shouldn't be a big deal. The caps aren't functionally important, but there will be a gap on the top of your sash. What do you think? Do you think you can adapt the 18-009 to your window?
