How do I mount to engine stand?

Pulled my 318 out of my Dart, i pulled the bellhousing and tranny off and know it just has the flex plate and something else, I don't believe it's a torque converter... Maybe clutch? Anyway it's attached to the flex plate and I'm having trouble take this off so I can mount the engine on the stand. Also how do I mount the engine? I own the harbor freight engine stand.... Bellhousing holes on engine look to small for the engine stand.
