MPH Speedo Face plate

[Wombat-007]

Hey everyone, does anyone know where I can get a speedo faceplate in MPH. I have you converter on the way so looking to get the face changed asap. Not wanting to spend the £400 or so on a uk spec speedo (thats half way to a decent V-mount), and the only ones I\'ve seen are the white plasma dials on e-bay or the MPH sticker which I don\'t really want either.
 
Any help in the right direction always appreciated
