We'd be happy to help but I'm afraid I'm not sure what kind of "flaps" you're looking to replace. If you could show us a picture of the part in question we can go from there. Thank you!

Hello Casy I have sent you two photos and I am looking for missing plastic flaps

The part in your photos resembles our 38-173 and 38-174 cam handles. Take a look and see how the dimensions compare to yours. Thanks for posting!
