Madeline:

The two door shelves are the same.  And then there is the
wire bail that is on the bottom one to keep one quart milk
boxes and the like from tipping.  I do notice in pix of
Westies for sale that the fridges usually looked stripped
inside.

A few years ago, I ordered some of the shelves and racks for
the Dometic through my RV dealer.  He looked on an ancient
microfiche for the part numbers, then called Dometic for
current prices.  They had shelves, racks, munchkin ice trays,
etc.  So find an RV dealer who will order from Dometic and
see if you can still get them.

You might also try DometicUSA directly.  Their customer support
number is 800-366-3842 and their spare parts number 574-294-2511,
but I bet they'll send you to a local dealer.  Let us know
what you find out.
