Hi my daughter has had a slow hit (lamp post)on her 1999 1800 sport v reg mk4 silver the tail gate is pushed in ,as the car is not worth a lot i am thinking of replacing it with a part from a scrap car . what problems can i have ? How does the wire fit through the body? and could there be problems with the lock ? at the moment the boot (tailgate)will not open. Are all mk4 tailgates the same or will i have to get correct year ?
