okay so i need a new clutch kit and bearings and things for my gearbox i believe the series 3 vs came out with the 5 speed getrag gearbox i was just wondering whether or not it makes a difference if i decided to buy a second hand gearbox and clutch whether or not i could use the vt,vx,vu gearbox and does it matter if the car was a v8 would it still suit the v6 thanks hope this makes sense cause it is confusing me....
