I just installed white face gauge overlays on my 02 v8 LS. I live in Canada so the only ones I could find are the ones from the USA with the large numbers in MPH and the smaller numbers in KPH. This doesn't bother me at all because I grew up in "MPH". My problem is at night when the dash lights come on not all of the individual number light up because the MPH and KPH are not exactly equal and do not quite overlap each other perfectly. So I wanted to know if the black painted face of the stock gauge cluster can be removed where the numbers are so that the green back lighting will illuminate through the new numbers on the white face overlays. Can it be removed by fine sanding or other means. Any advise or experience would be appreciated as I really like the white faces and want to keep them.
