Just take the one they send you and make your own from a real 1/4" plywood or equal product, this one they send was a very thin carboard (thinner than a legal pad cardboard) and tore easy, holes did not match nor did the knock out for tubing or for the water line. there was no holes on the bottom of the fridge to mount and had to make my own. The only reason I say that is because the cardboard warped out of shape and would not allow the air to flow properly. I made mine from 1/4" hardboard flooring, transferred the as much of the right holes and made the rest to fit.
I have purchased many, many items from sears parts direct and this is the first item that was not worth the money. "Sorry Sears on this one I don't think you made it but you did ask"
I really just needed to see the air holes from the coils to the compressor or I would have just made my own anyway.
