Might want to use the sealed bearings on the adapter. It helps keep the tranny fluid from getting into the tcase. Also the drive gear nut is a 1 time use lock nut so it will need replaced. You can get all the parts from AA. I got all the bearings,snap rings,gaskets and nut to rebuild mine for around $100. I've been told you'll need to modify the tranny pan to clear the front drive shaft also.
