Good luck with the car. Verts rule.
About the top, are you talking about reinstalling the back window and not replacing the whole top? Its a pain in the rear to do and sometimes its better to let someone who has done it before show you. Get with some local stangers and they can point you in the right direction. I have always replaced the whole top once the window and surrounding material starts to get bad. It usually is just a matter of time before the rest falls apart.
