help me identify these 4 speeds!

You and oldkimmer are right on the first one. The second is either an A or F body. Looks like an A body to me. Measure the diameter of the bearing retainer on the input shaft. If it is around 4 1/2 inches, it is for an A body. If it is just a little over 5 inches, it is an OD and came out of a '76 A body or an F body. Also check the shift levers. If they are both pointed up it's an A body. If the front lever is pointed down and the rear one is pointed up, it's an OD.
