Classic Winnebagos & Vintage RVs

Hello, this is my first post so I hope I am in the right place.  My wife and I are replacing all the drawer and cabinet pulls with ones my wife prefers.  We got to the vertical pantry pull outs are are stumped.  The screws for the handle are not accessible from the inside.  We believe the fron of the cabinet comes off to access the screws.  There are screws down the front side that hold the front on, but nothing on the back side.

Does anyone know how to remove the pantry front to access the handle screws?

Thank you for the help.
