I am looking for aluminum replacement jams/tracks for my windows. I want to remove the chain/weights on my wood windows and replace them with aluminum jams/tracks with parting strips that have springs within them and compress against the windows to hold them in place. Can anyone tell me where I can buy these kits? I think they may be called CBW tracks? Thanks, phrm

Try a door/window company. They may to order them for you.

Did you ever think of replacement windows instead of going through the trouble with the liners?
