Does anyone know who makes the female 'cone' parts that fit in the bodywork? Sadly on my 2003 Plus 8 the left side looks to have split, even though it is metal. Also when you pull the cable there is no metal 'tongue' visible on the left side moving side to side, which there is on the right. I have a feeling this is going to be expensive, but necessary as the front left side of the roof flew up today on the freeway which was quite entertaining.
