After an unsuccessful attempt to manufacture my own for my 16.49-1 (the velcro adhesive let go of the clear vinyl in the heat) I stumbled across these on ebay:

I ordered these on Friday morning and they arrived today in the mail. I am very pleased with the quality of the product. They are placed between the flyscreen and the skirt and can be left there permanently as they have their own zippers and can be opened in summer. They are available as crystal clear or the weave style. I ordered the crystal clear and they are very clear and flexible.
I have no affiliation with the supplier, just a happy customer.
