Dear Folks, I am attaching a scan of the weatherstripping I am looking to replace. The bubble is eliptical and measures 4/16" x 5/16". Can you please confirm that your bubble weatherstripping 58-053 is what I need.

It does appear the Swisco 58-053 Bubble Seal is the closest match to your original.
