Probably all of them.

If a part is only for a specific range of years, then it would say 12/1989

- 11/1993 for example, indicating that part is Rev1

/ Rev 2 only.

from the top of the screen the parts chap is looking at 12/1993, which is Rev3.

If you refer back to my screenshot, 31105G refers to 4 different bolts

(see the other parts in that group are highlighted red), which is why it lists multiple options.

It also tells you the spec of the bolts so from that you can work out which one is which, if you're after a specific bolt only.
