Traco window guidance

A handy person from Chicago says:
I have been asked to repair the spiral balances and tilt locks on several aluminum double hung windows in a Chicago high rise.
Based on the information stamped into the glass panels, I believe they are Traco windows

Is this the part(in blue) that would be needed? Do you stock them and how does one install it? I didn't see any obvious screws that suggest where to take the frame apart.

Also, I've noticed that the spiral balance tubes move around a lot when the window is down and interfere with the tilt locks clicking home. Perhaps this is how they got broken. Any thoughts or suggestions you might have would be greatly appreciated.

For this Traco TR-5000 Commercial window, the white nylon tilt latch you are looking for is the 26-069. It is attached with the 26-016 spring and 26-017 retainer. The finger lever meanwhile is the 26-002. I pulled up a slide latch diagram to help you. As for the Series 600 balance tubes, they need the play because of the tension of the spiral.
