Here's the spacing as close as I can measure on my '66 MK2. I know the bonnet has been repainted so I'm not sure if these measurements are 100%, but they look a damn site closer to "correct" than my wife's '67. Linwood tolerances.... ;-)
Some are measured from the flats of the letters, some are from the serifs. If I drew I line through the serif, then its measured from the flat.
