Replacing Defrost Hoses for 1971 Demon

I have new hoses to replace the make shift set up that's currently in there. Is there an easy way to do this get to the vents? Do the vents pop out from the top? Undo the dash? This is a pic of the passenger side defrost hose with the glove box removed. ( sorry for the upside down photo)
