Transmission!!???!!! HELP!!!

Guys I am asking for help to get a proper working trans in my 67" Valiant so I can start having some Relief from all this craziness. I have a line on a trans but can not identify! I being told it is a 3 speed with over drive that will bolt up to my bell housing. My Valiant has got the three on the tree with the factory 6 cylinder. I am going to try to upload the couple of photos I have and the casting number on the passenger side is C 95039 U. Also I'm being told it is out of an A100 van if this helps. I HATE 2020!!!! 3spd trans 1.jpg 3spd trans 2.jpg And if the last photo helps, it is the one with the flange that bolts to the end.
