Stanley (Murray) GT Sleeve Hitch Help Please

I have a Stanley GT, i think it's an '04 model, made by Murray. I am about to purchase a sleeve hitch to fit on it, and was referred to the following thread about how to make a Craftsman hitch fit on a Murray:

The problem is, i can no longer find the sleeve hitch with that model #, all i can find is the one from the Craftsman site:

Does anyone know if this sleeve hitch is the same, and can be modded to fit the Stanley? I'd hate to buy it without knowing.
