Installing old ice maker in new freezer

I was able to transfer my old ice maker from my old Roper Refrigerator/Freezer into my new Whirlpool Sidekick Freezer. Everything transferred directly except for the water fill tube. I ordered one on line and simply cut it to the right length, removed the cover plate inside the freezer compartment and the little sticker from the outside. Inserted tube and fastened in place with two screws (not provided but was able to use the screws that were in the holes inside the freezer before the ice maker went in. Works great. By not buying the ice maker with the freezer I saved a hundred bucks or so.
