We are talking factory convertible, right? If not ignore this post.
The installation of factory roofs is not a simple task if you want them to fit properly. They are very complex things & have heaps of different places for adjustment where if the installer has no experience, the results can be poor. I'd be worried that you got someone to (try to) do it & they stuffed it up, you don't want to pay, yada yada yada = a bit shit-fight!
Try these sites:

http://w1.telia.com/~u31614242/cabkey.html
The best one I don't have anymore. (Haven't had a cab for a long while!) But if you do a search for Chuck's Convertible Supplies in California ( where else??) he was selling replacement roofs world wide BUT he also supplied a fitting video which he may be prepared to sell.
Good luck!!
