Brian,
Did you get your top replaced yet? I just had my (first and hope the last for awhile left cylinder) go bad sent it off to top hydraulics. Looking forward to posting some lessons learned with pictures. We have used the 3M glue with clamps to repair the glass to top situation and has worked well for me but I know that the top will have to be replaced one day. I got quoted 3700 here in Norfolk for top and replacement.
