You can upload your images directly to this thread. I'm not sure if our 38-090 is a match, but your best bet is to carefully compare your part to our pictures and dimensions. If they differ in any way, let me know. Do you also know who made your window? American Craftsman and Silverline both only used the 38-090. That may give you a c lue.
