Good eye Claudia.
I guess I'll take mine apart and figure out why the odometer won't spin. The way it is now, I can't accurately measure fuel mileage - WAIT - I almost forgot - who cares? It's a diesel, so I know I'm getting better mileage than you gassers anyway.

I think the difference is that pre 09/73 clusters didn't use "solid state" components - I bet you haven't heard that term since the '70's.
Please take a picture of the front and back if possible.
Thanks,
Dan
