I'm still not exactly sure what you want to replace, so let's just describe the differences.
The Crank, Rods, and Rod bearings etc are the same. What's different is the bore size and the location of the ports. So, if you want to swap the cases, you won't be able to. If it's just the crankcase head you want to replace (part #0385502), that's the same.
