Gebhard; I am replacing my 89 3ooe trans in the next few weeks. I have done extensive research on this subject and have a lot of names and numbers that may be helpful in acquiring a trans, but get ready to spend some money. They don't come cheap and installation is your responsibility. I'm going with the TBR Donnie recommended, but don't waste your time calling them directly, they won't talk to you. I can guide you to some very knowedgeable people closely associated with this forum who have helped me.
