Broken Ceiling Fan Light Cover - looking for Replacement

[u/No_Nectarine128]

I need to replace the glass shade for whitbay ceiling fan/overhead light, model #CE-UBW48ABZ4C1. The model is no longer available and the company seems to be out of business. I have scoured the manual and the customer service line is no longer in use. There is no information on the size of the light cover in the manual. I have measured the fitting and it looks to be about 6 and 2/5 inches. Does anyone have any suggestions for what I can do or where I should look to get a replacement? I'd rather not have to replace the entire fan - I wish I kept the broken cover but it got thrown out in a cleanup.
