thanks for the replies chaps - at least it looks as though I can get to the window from the inside of the door.
I have had the door card off loads of times, so I can do that with my eyes closed - but never really had a nosey with the glass. Luckily I have a day off tomorrow and for the first time ever a garage to do the work in, so ill be getting stuck in!
To be honest if I can get the window back to the top and wedged in place thatll be enough - middle of next month I should be getting a 350Z and then the Spider is getting laid up for a major overhaul/restoration.
Got to love Italian cars eh!
