Windshield sealing? lock strip

dengit...just got back from a trip and went out to look at the glass. Rear weatherstripping is completely different from the front, and the front, though slightly different than the pics above, still has that slit. I will fiddle fart with getting the lock strip into the front stripping, but what about there rear?

Front on my car:




Rear (yea, so it's a little dirty...primer doesn't really ever look classy :P):
