Probably not much chance of this, but you never know

I would like to change my Mk5 Speedo to read in KPH. If I was to use an overlay (as on ebay) it would make sense to go for an upgrade to white, but they naturally only do MPH. So the Q. is. My top choice is white overlay in KPH, or second choice Std grey unit in KPH, any ideas where I might source...

Thanks
