After using the rubber mallet method to split the cases with no luck I decided to build a tool to do it. I removed the two studs on the top of the case that have a section of case between them on one side but not on the other. I made a plate to bolt on the back side of the two stud holes with a jack bolt in the middle. I used an aluminum softening plate under the jack bolt. After getting a little seperation, I used a rubber mallet to split them the rest of the way.
