HELP!! Bought new Dometic refrigerator--How do I remove the rm60?

[Shelby Copeland]

I have a 1974 Trade Wind with the Dometic rm60 refrigerator. It works fine but my wife says she wants a new one. Well we bought a new Dometic rm2510 and now I need to remove the old and install the new. Sounds simple but I can't figure out how to get it out. I have removed the tambour door above the refrigerator and have loosened the cabinet top above the refrigerator on the right side but I cannot release the left side without getting the refrigerator out first. I can't find the screws that must be holding the refrigerator in place. Also--- the new Dometic is 1 inch taller than the rm60 it is replacing--cabinet alteration here I come. Now why did Dometic do that to me??? SOLUTIONS AND SUGGESTIONS will be greatly appreciated. Also the working Dometic rm60 needs a new home. I do not know its value. Thanks in advance for any help.
