I have a cabin built with "snickar glädje" by someone who used whatever they found 
Anyway, I have a sunroom where one of the windows (there are 5 different types of windows) is a sliding window.
There is a two-track rail both above and below that is about 1cm deep and 4mm wide, and below should be a plastic/silicone strip about 5mm deep. The glass (just 4mm float glass with nothing extra) then slides on the strip and lifts the glass into the upper rail after installation so that they don’t fall out. The problem is that half of one strip was already broken, and when I was renovating, the other broke in the middle. And I can't for the life of me figure out what to search for to find a corresponding strip so I can replace the old ones which are probably at least 25-30 years old.
The rail looks approximately like below, but deeper.
