Okay boys...Now if the metal strip covers them ( slots)how does the air flow up the inside of the windshield to defrost them?

The deflector/cover does not close the openings/slots, it goes over the slots. There should be "stand-off" clips under the cover/deflector. The cover/deflector very effectively deflects and spreads the warm defroster-air against the windshield.
When you get home,
take a look at this image, look at the deflector strip in the image, and then look at your deflector strip.
Do you have an original radio? That will make it harder to see how to deal with the vents from under the dash. That is why I suggested above that you consider removing the deflector/cover so that you can better see (visualize) how this works.
