5.9 magnum flywheel on 5.9LA

Isn’t the nv3500 the one with the bellhousing built onto it? I’m having a hard time finding the transmission, buddy gave me the gas bellhousing.
Yes the NV3500 has the bell housing. Have one of those in my Dakota. I'm not sure about the NV4500. I was told the 5.9 unit did but the CTD unit didn't.
