A lot of the parts are probably interchangable.

The one on the upper right doesn't appear to have a stop for the tabbed washer, so that body wouldn't work. The one on the upper left looks like it might have the stop.
Both on the bottom have the tabbed washer, obviously.

The long cages should fit on any of the bodys.
As they are all grubby, I would recommend taking them all apart for cleaning, and then rebuild one from the nicest parts: best jockey wheels, best body, best cage, etc.

I'll bet you have enough parts there to put together a nice one with the long cage, tabbed washer, and mounting bolt you need.
