HI EGG
YOU TAKE THE CLOX OFF ,TAKE THE FRONT OFF(screws behind)take the clock off the cluster,by undoing the screws holding wires on.
To correct clock if necessary(different sprockets),kph-mph if left-hand drive speedo ,do any maths that are needed,then drill tiny holes(1mm) where the new 10 mph increments come.(ie 90 may become82).
Remove the 2 tiny screws that hold the face on,then scrape off the black face,& numbers,then rub down with fine wet&dry.
Go to your local model aircraft shop, and buy a roll of white "SOLARTRIM", (if you use any other source of white vinyl,you
are on your own regarding translucence for the back lighting).
Cut out a circle oversize,roughly cut out the hole for milometer,make a cut from this opening, to a small hole in the middle,for the needle shaft,now remove the backing, and CAREFULLY,position,and stick it down,smoothing out bubbles(pricking with a needle if needed_.
Trim neatly,then use 6mm LETRASET,using the I,or 1,for the lines,then reassemble,fit a higher wattage bulb, and off you go.
