w211 speedo
 

bought a 2004 e500, was originally a canadian car so speedo numbers are kmh...when car was imported someone just put a mph overlay on it...looks ok during day, but at night when gauge backlights you see kmh on gauge thru the overlay and it looks a mess.....in fact cant read it.


I see used clusters for sale, can I swap them out without mileage reading problems? Can I just swap the speedo? or perhaps the speedo face??
