Ice and Water Dispenser Funnel

Question

My rubber funnel broke off (without even touching it) in less than a year. Ge did replace it but it is without the rubber funnel. I assume the plastic is longer to accomodate this.

All I am looking for is how do I replace this?

All I need to know is how to remove the front dispenser panel to get to the insides of the freezer door to replace the funnel (part # WR17X11966)

Thank you
