husqvarna 456 bottom metal

About a month or so ago, I posed a question about replacing the aluminum bottom metal on my Husqvarna Model 456. One of you gents sent me a note about photographing the stock and floor plate. Can't find the guy's email. Anybody out there have a suggestion for a replacement bottom metal arrangement? I want to replace the aluminum one piece unit with steel. Would the older Husqy Model 4000 metal work? I believe that was steel.
