This would seem logical. But I thought the internal gearing was different 
on the speedos originally. Even if so, a recalibrated face would be an 
easier fix. When I first changed my o/d, I just put a couple of small 
pieces of scotch tape on the side and then made marks for 60 and 70 mph 
which I determined by a long highway drive, timing the intervals between 
mileage markers.

67 BGT
71 BGT
