You could have 2.73's, 3.08's, 3.27's, even 3.55's, all depending on what tranny and what gear option (if any) was chosen when the vehicle was purchased.
If you have a manual, I'd go with 3.73's (maybe 4.10 depending on whether you value gas mileage). If it's auto, 4.10's are a must.

If you still have the factory bell housing on your rear-end you can find out what kind of gear you had factory. There will be a small metal tag bolted on with one of your cover bolts. On it will be a series of numbers and letters. Mine on my 98 had this:
3L08 = This is a 3.08 Trac-Lok rear end.
3L73 = This is a 3.73 Trac-Lok rear end.
308 = This is a normal 3.08 gear.

Trac-Lok is basically Ford's version of the Posi-Trac setup. It's clutch driven instead of cone type. The good thing about the clutch type is, if it breaks or wears out you can have it rebuilt. I had my clutches modified and I have 3 on each side, instead of two. If it's not Trac-Lok then it's limited slip.
