More instument cluster problems

Aside from the tach and water tem gauges not working, the speedo functions but the odometer and trip odometer are not working. The oil light also stays on but there is apparently no oil pressure problem. This is all new to me and have sorted ourt a bunch of other small problems.

Any ideas?

Odometer problem is most likely stripped gears. very common problem. www.odometergears.com they are like the only place to get replacement gears. Its helpful to take your cluster out to know what gears you need and what time of cluster it is (montronic, vdo)
