I assume that changing the red line marking is what you were trying to do...

I used black sharpie and "changed" the red-line on my vx tach. It's not really all that noticeable, but the 6 mark and numbersare still red. I don't care... because just like it says on your avatar, I too drve a #@%^ing egg.

How did you break them?

I have an extra CX cluster you can have, which has the same bezel as the rest of the 5g hatches (if all it is is the lens or bezel that's broken) and the idiot light lenses are interchangeable, too.. There are only a few screws holding the guages into the cluster from the back.
