Odometer Reset

Hello, the factory gauge cluster on my 1992 B2200 didn't work. So I went to the auto wreckers and got a new one the problem is that the wreck I took it it out of had 50,000 KM more than my truck so I want to roll it back. Does anyone know how?

I reset the one i just bought, unfortunately i didnt take pics. took the guage out, pulled needle off, 2 screws holding the face on, the part with the numbers on it is held in by 2 plastic clips i accidentally broke one side, then i slid it out of the other side. moved numbers to where i wanted them. Then put it back in the tabs, glued the broken piece back in. Then used a solder gun and melted the plastic together(backup for the glue)

if you can get it out, take the numbers off your old one and just swap it over.

Sorry no pics, maybe ill take it out and see if i can get some and make a thread. Heck their might be one here ha. havent looked
