Odometer fix?

Its his spedo/odometer he took apart.
Correct. The odometer was taken out and thought I could pop it back in. I can get it in but the numbers are wonky. As when the lowest number moves instead of the next set of numbers rolling over it moves all the numbers. Didn’t know if the little tabs are set against the steel bar or notched in. I have a 64 cluster I might use as a reference. I should have left it alone in hindsight.
