I think my speedo is out on my 93 Type RA. I've been told my gearbox was changed to UK spec gearbox, the cable has a converter on it, is this needed if running a uk spec box? I have the speedo that reads 180mph. If running uk box should i have speedo face that reads same as uk spec car(what is this?) and not use the convertor on the cable. Oh dear i think i just confused myself!!!!
