I didn't realize I ordered one rubber seal. It would have been nice if customer service thought about the order and thought "this customer needs two" and gave me a call/e-mail to confirm. If customer service reviewed all orders then they can better serve if the customer actually needs or doesn't need something. My recent order history includes the glass and new windshield inner/outer frame, external rubber seal, cowling rubber seal. Now that I have a 3-day weekend to do all this. I can't finish the job because I need one more rubber seal for the other sheet of glass. Its my fault, for not checking, and frustrating.
