TRACO window tilt latch

Looking at your pictures, I would recommend our 26-002 sash release lever as well as our 26-069 tilt latch, 26-016 spring, and 26-017 retainer.

To replace the broken top tilt latch, remove the sash from window and unscrew the top rail. Lay the sash on a table and use a block of wood and hammer to carefully knock off the top rail. Now you can remove the latch with the spring and retainer. You can reuse the spring and retainer if they're not broken and just replace the broken sash release and tilt latch, if possible.

Well, Traco has been known to use the Series 600 spiral balance, which has a 5/8" diameter tube. But I'm not sure if that's what you have. Give it a look and see how well it matches up!
