Searching for Broken plastic shoe for double hung window

Hello, I'm trying to find a shoe for my window and cannot see anything on your website that matches. Attached are 3 pictures a picture of the shoe in the vinyl channel and a picture of the bottom of the shoe that is broken and also the top of the plastic channel track that the shoe runs up and down in. At the top you will notice a plastic "stopper" which I think holds the spring system in place. My house was built in 1994 and I see no evidence or indication who built or made the windows do any help or advice you can provide about the shoe and how to replace one would be really appreciated. The shoe is plastic and is 2 1/4 inches in length and 1 inch wide. I hope you can help. Thanks in anticipation Duncan

Hi Tom, thanks for your reply and while the shoe that believe is the same as mine looks different to me I will place an order for a couple and see if it is a match. I do have another question and that is do you know how to remove the shoe from the jamb liner on this particular window and also do you know how to remove the stop? Thanks in anticipation, regards, Duncan

Hi Tom, Thanks for your reply and once the part arrives I?ll see if I can manage the repair and if not will seek professional help. Thanks very much for your advice and timely responses to my questions. Sincerely Duncan
