Replacing Defrost Hoses for 1971 Demon

Wouldn't it be nice if those vents popped out, hose shoved in from top down? Sadly that's not the case. There isn't a easy way. Pull the glove box liner helps access the right side vent.
I did purchase the reproduction kit from DMT. It aint OEM perfect reproduction but does include the adapter for different hose port diameters ma mopar cursed us with.
