Replacement part for double-hung Jeld-wen windows

Our house has double-hung wood Jeld-wen windows. One of the uploaded pictures shows the overall window. On the side of the window, near the bottom, is a metal piece that fits into the window frame and that travels up and down with the window. As you can see from the other picutures, that piece has gotten bent.

Do you sell replacements?

Thanks,

Josh
