Ha ha, not stalkerish at all. Yes, that's my poorly zed and no problem over a picture - first time I've seen her without her clothes on!

Thank you so much for taking up the quest, I too have been trying the various routes advised by others and had also heard the carbon fibre rumours but am also lacking in actually finding any panels - even trawling the German and European websites.
In case of interest to another BMW aficionado, as you can see my Z1 has been converted to right hand drive but also was one of a very select few that was converted by Griffin Motorsport (now defunct I think), so rather than the standard 2.5ltr from the 325, it has been bored out to a 2.7ltr and has various other tweaks to give it a little more performance in line with what the very capable chassis can handle. Anyhow, I digress!
Being in Falmouth, there are a number of very skilled boat builders/repairers here and as a last ditch resort, a friend is having a word with his 'composite guys' to see whether they could make a mould off the existing wing and then create a new glass fibre panel. Having said that, I am surprised that KJRule have said that one of the wings is irreparable because following chats with other Z1 owners, they appear to have had worse splits and have managed to repair them with plastic welding? KJRule have advised that they have they right equipment for plastic welding but there was a lot of fizzing and bubbling and they were worried the panel would distort (....or perhaps has and hence is now irreparable?!) KJRule were recommended to me and indeed had the car in just over a year ago to repair a split and that's why it's back with them as the repair hasn't lasted very well.....having said that, on the plus side, their painting and colour matching was absolutely perfect! Perhaps, it's worth me talking to Autostyl, in case they have more experience with this polycarbonate material...?
