Fiberglass window covers/ awnings

I have an older Jayco which has a fiberglass awning/window cover. I have tried to find a replacement but Jayco does not carry anthing for a 1991 travel trailer. If there is a co,man y out there that makes aftermarket fiberglass awnings I would love to know ho they are. If it isw a little too big that is cool I can make it fit, as long as I can get the hardware to install it. thanks Chaggy camper
