EL Fairmont wagon - Drivers door wind noise

[Way2go]

Question re our EL Fairmont wagon.

Does anyone know the part name or number for the rubber block that is attached to the lower part of the A-pillar (and aligns with a similar rubber block on the door)?

Took the vehicle for its first highway drive yesterday, and noticed some pretty serious wind noise up around the top of the drivers door. The only thing I've spotted so far is that the above-mentioned rubber block on the passenger side has no gap between it and the rubber seal that runs up the front edge of the A-pillar, but that there is a fair gap on the drivers side.

I'm assuming that the rubber has somehow gotten deformed over time on the drivers side, and that this is all I need to replace. Hopefully they are relatively cheap and easy to replace/refit.

Anyone else experienced this and was the rubber block the problem - if not, what was and what was the remedy?

Many thanks.
