Need Help - Odometer/Trip stopped working!

[Fender1325]

realized the damn thing cut out. Its a 98 GT with the mechanical odometer trip, not digital. The speedometer and tach and everything still works but the odometer and tripometer stopped at about 121,XXX miles.

I wouldnt exactly care but now I cant tell when I need to change my oil. Can anybody help?

just noticed a similar post below me, so I'm assuming its just a broken gear? Anybody know where to get the correct grease?

its different than that 94, mines a 98 so its a different process. Does anybody know how to fix a 98?
