i do have the torque converter, but i would not use it unless you get it rebuilt. the reason i swapped out the trans transfer case in the first place was that there was a small whining sound when put into gear. neutral was fine, but when it had a load on it it would start the whining sound. it worked just fine, trans shifted great, no slipping or sluggishness, everything was working perfect, just had that whining sound. i ended up selling the jeep before i had the torque converter rebuilt or replaced. the one i swapped in was working good so i didn't see the need. they are still bolted together and even to the crossmember.
i do not know anyone that commutes to LA, but you can ask in the chapter forum to see if a parts train is possible.
