Hatchbacks came with glass. CRXs came with metal. If I am not mistaken you have to pull the whole assembly out to change out the glass, but doing that is pretty easy. If you take the headliner out, you will see all the bolts that hold it in. Unplug the motor, disconnect the drains (one at each corner), then pull all the bolts out. Have a friend with you, that assembly with the glass is HEAVY.
