speedometer suggestions

volunteer said
(tee, hee) - Now that we are on the subject of speedo numbers, does anyone know if there are decals available that replace original MPH values with Kms.PH. - for garden-variety '69 Valiant? For example, with speed limit at 70 kph, it is difficult to instantly calculate corrected 43 mph. :)

remember the old commercials. 20 gives you 30, 30 gives you 50, 50 gives you 80, and 60 gives you 100. you will do fine just sticking to traffic flow.
