Thin vent window seals?

[Skunksmash]

I recently replaced my vent window seals and well... I have to say I'm not impressed. They're the exact same ones that you can still find at some of the dealerships here and there. Can't remember who the manufacturer is but they're somehow thicker than the originals. By a lot.

Got the old ones off and they just fit better. And you can just tell by looking at them that they're not the same part. The new ones fit ok I guess, but you can tell they're some kind of aftermarket. But, its what GM ok'd for some other company to produce, so I thought it would be my best shot. Anyone else do this job somewhat recently? If so what seals did you find? I ended up having to use clear silicon to go over the leaky areas. I kind of peeled back the new rubber and put it behind there so it wouldn't show.
