identifying T5's

[sofa king]

I've got 2 that I would like to sell, but I am trying to identify what they are from. I know Mustangs, and I am almost sure one is from an SVO, the other from something 87-93.
The stamped tags are MIA.
Is there any other way to tell? I am also pretty sure they are both from 2.3's....Input shaft is different dia, I know that much.

You could measure the diameter of the shaft where the pilot bearing rides. That will get you close to knowing what it came out of

Just from looking at the outside of the case your not going to be able to tell very much.
Removing the extension housing and top cover, identifying the syncro type and counting the teeth on the gears is about the only way your going to tell.
