Sounds like your in the same boat as I was. The bearings should be pressed into your case halves. If they do not fit in there tight enough without play then your case halves need to have inserts made for them that will fit your bearing properly. Once again I had Jerry Hall do mine for me. He did a great job on them. If you have those done you might as well have the sealing surfaces checked out as well, They may need some machine work to ensure they are flat and fit together just right.
