edde said:Might be a daft question but does the 172 gearbox you have come from a phase 1 / CUp as you'll need one unless your speedo input comes from something else as the Mk1's use the gearbox sensor to detect speed the 172 excluding the phase 1 some early phae 2 (very few) and Cups didn't have gearbox sensors as they use the ABS system.
I believe its a phase 1 gearbox im getting but its coming with a speedo sensor, made sure it has. Got it from Cit-ren coming down thursday so ill find out for sure then.
