That opening you see on the seal is to accomodate the center support of the wind deflector and it should be mounted on the bottom with the fold on the top.

I´m sure you already know this: the wind deflector must be removed along with side felts to do the job correctly.

The ONLY seal that will fit correctly is OE. With a little silicone spray, the OE seal will intall easily in about 30 minutes.
