Hey there,
Thanks for reaching out! We are certain your window tracks are no longer available. I have seen this type once or twice before when I was removing them to install new vinyl replacement windows. The way your sashes are shaped on the sides prevent you from using another type of track or balance system. However, if you do want to try and repair your window, I would suggest purchasing some type of screw and washers at a local hardware store.
Take the track with you to show them and maybe they have a type of washer and screw that could help secure the tracks in the window.
To lubricate the tracks, I would suggest the 75-077 slider track lubricant, or an equivalent furniture wax polish (I've known people to use old candles in a pinch!) You can also use a type of silicone spray or even a type of furniture wax polish. We advise against oils like WD-40, which can collect dirt and debris and clog up the wheels. You want a lubricant that is dry.
