Rear window weather strip removal

Even if you got it in nice and tight I think time and fluctuating temperature would cause the joint to separate and leak. I'm not even sure how you would get it in since the whole thing is installed in the pinch weld and then the glass is put in place into the gasket. Sounds like a nightmare keeping the gasket ends where you cut it in place while putting in the glass - just my 2 cents. The "cheap gaskets for my 70 Dart have " square corners" in the bottom, so adapting that $100 gasket might not work - those gaskets have no locking strip.
