Help identifying 4 speed transmissions

I have five 833's and im trying to ID them. I need to find out which one would be best for my 71 cuda. I think two are E body and one A body. The others im not sure of. Four of these have pads with numbers but one does not. Im posting pictures of the one without numbers. Here are the numbers from the others.Of course I cant find my 833 book I bought 6 months ago. Any help would be appreciated.
