I just installed mine last week that I bought from
www.topsonline.com. It took a month to arrive which was irritating, but was a great canvas top at a great price. If you want to install it yourself, plan on it taking a while (it took me a week, but I also only got to it an hour or two a day) and ensure you read/print out this post done by a member "gadwhite" which I did. The link is:
Convertible Top Installation Project. It takes a while, but is possible.
