GB rebuild to km/h?

Hi!
It seems like the digits in km/h on the miles tachometer on my GB gets smaller every year.
Is it possible to switch to a km/h tacho from a XBR into the chrome GB housing?
Any other tips how to solve this?

No problem, fits exactly.

Thanks Kurt.
No modifications needed, just "plug and play"?
Then I'll try to find a XBR tacho.
