Hi I have attached a pic of my MPH speedo on my 71 LHD Montreal.
Thanks Rob, now that I see your 'MPH' speedo I realize that it is identical to the one shown on page 28 in M-tEC! It is not at all what I am used to looking at. The interesting thing is that your speedo face not only has MPH but it also had Km/Hour on the inside. Now why did Alfa not just use that speedo face on all of their gauges? It would have made sense to me.
I did get a reply from Delmas Greene regarding the speedometer face 'clear vinyl overlay' and he does have one that he is using on one of his Montreal's. When there is more information available, it will be posted here.
