Misshapen '68-'69 Fastback Gasket?

Hey FABO,

I'm looking for a little help with identifying if I have a bad gasket or i'm just plain doing something wrong! I bought this '68-'69 Fastback rear-glass gasket off of YearOne since I converted over to the '68-'69 chrome trim on my '67 Fastback.

No matter which way I look at it, there is this extra ridge of rubber that runs along the entire top portion of the gasket. All the other portions of the gasket appear to be fine, but this ridge extends far enough to cover up the trim when it gets installed.

Did I just get a lemon that I need to return, or is something else wrong here?

Thanks!
