i think those guys answered your question. the gasket has to be on the windshield first and of course the dash must be in and centered. i'm not sure but i'd think your gasket would be the same as my 69 rr, without the locking bead. it is important to start the bottom in first. at first it will look like it won't fit but slowly it works it's way in. just don't be tempted to pound on it too much. good luck.
