[11th Indian]

I found a replacement gas gauge for my 72, the original face-plate was worn and rusty.
The replacement is from another vehicle of undetermined origin. (GTO, GP, 70, 71 72 etc...)

My question is are the gauges from different years that look exactly the same, electrically the same?

Can I just switch the resister on the back of the gauge from my exiting unit, but the movement is otherwise the same?

Thank you!
