Brittle Plastic Coil Supports

A quick learner from USA says:
Hello
I am sending you a picture of my broken window coil spring assemblies

Actually the springs are good , the surrounding plastic is brittle and breaking.

Please let me know if you have these replacement parts and what other information I need to supply you with

My other question is that , I do not see how the old parts come out of the window tracks . I have searched on the internet and it seems like there is supposed to be a slot in the window channel but my windows do not have a slot.

Thanks for the images. I recommend our 15-144 and 15-143. As for removing the hardware, see the video below for a possible solution.
