66 dart dash removal

I am ready to remove the dash on the Dart. I did a search and everything I find says that the windshield needs removed, however I think those post are for newer darts. I looked under the dash and I see what appears to be sheet metal screws at the top near the windshield. Inside at the bottom of the windshield there is a plastic or rubber trim that I think the heads could be under there. Is this correct or does the windshield have to come out? Also if the strip can be removed to get to these screws where can I get a new trim? Again this trim is just below the windshield on the interior side.
Thanks
