I have a 25x36 window in my bathroom from 1987
I need to replace the cords or lift unit

Can you send the part#

Thanks for posting. I'm afraid I'm not entirely sure what you need. Could you take pictures of the parts you need to replace, removed from the window if possible? This would help us narrow down what you need. Thanks.
