how hard is this to fit? and my rev counter needs fixing or i cant run at york. any suggestions? it pissed me off last time having to guess when to change gear. im sure i can knock a tenth off with it workin. going back to the mount thing, when i plant the throttle there seems to be a bit of movement in the engine/box, is it likely to be this? cant afford the lot doin til i sell the punto so iv decided a hillpower uprated jobby is what im going for.
