Thanks Vombil,

I have the two bows and the holes are there, including an extra set which I don't need to use. I went to start the fit up on the weekend, fitted the bows and then tried to work out how the back holds up. When I looked up I can see the clip/slots to hold the third line in the headliner in but I don't have the wire to go with it which runs along the front of the roof seam at the backbehind your head. There is also a hole each side at the same level as the bows and I am wondering if the wire clipped down to these holes.
