When I did new molding clips for my windshield what I did was took a guess as to where clips should go based on depth of screw hole.
Then I pushed rubber windshield gasket into place, no glass, and test fit molding. I rebent the clips to have less tension so molding snapped in but didn't require excessive force to get molding to seat. That way once glass is in you know for sure molding will easily snap in and fit correctly. Otherwise you might get glass in molding wont fit have to take glass back out.
