I've fitted a 2 litre 9A engine into my 16valve mk2 golf. I've also fitted a Corrado cable change gearbox (I believe it's a 02A model box). The problem i'am having is that when i'am driving, the speedo is reading 10mph faster then what i'am actually doing. (i.e when doing 30mph, the speedo is showing 40mph). I've narrowed it down that i have the wrong speedo drive that goes into the gearbox, that actually measures the speed. The cable and drive i'am using is what came with the second hand gearbox. So i'am guessing the previours owner must of used left hand drive spec drive that reads in kilometers per hour, hence giving the incorrect reading. Would anyone know the part number for the correct drive that goes into the gearbox. I've taken pictures to show what i mean, and it's the item in black that i'am after. Getting really frustrated with this
