Jamb liner and parts

I'm looking for a replacement liner like this or parts to fix these liners. Is it possible to get new pieces that attach to the sashes to allow these to function as intended? In most cases the plastic pieces have been broken so the springs are not longer attached to the sashes. There is no manufacturer name on the liners and I'm not sure of age. They are all metal and are 3 1/4 inches wide. Length varies by window as the home has several sizes of windows.

Thanks for your reply. Are there no current nylon pieces that are suitable for retrofitting these existing liners?

Thanks!
