904 question

Not sure what year the trans is. I'm just looking for a 904 that is non lock up that I can rebuild and use on my 340. What other vehicals would habe a 904 in them so I can look in a junk yard locally. My biggest concern is that I need to be able to use my TC. 27 spline non locking.
They were put in virtually all Mopar vehicles. Cars, vans, trucks. Just look for a small block transmission, built after 1968, lockups came on board around 1978.
