Windshield gasket for 67 Barracuda

I have a 67 Notchback Barracuda and have the original gaskets for both front and rear windows. I either need new lockstrips or new gaskets but don't know which way to go. Can I use 68 gaskets without the chrome pieces? The windows are currently just set in place with no sealer so the do leak in the rain and I have to take care of this soon. What works best?
