I just finished installing a new top, it wasn't too bad of a job now that it's done. The first time you do things is always the hardest, if I had to do it again I'm sure it would be much easier. It came out pretty decent, there are a few wrinkles I have to take care of but maybe at a later date. I was quoted $750.00 for labor from one local shop and $1,800. for a new top with glass and labor from another shop. He did recommend the GAHH brand, I bought a Sierra brand with the German cloth and the plastic window for around $390.00. So I saved the labor cost at least and the hassle of taking there and leaving it for a few days. Here's a pic of it and thanks to Mike Focke for posting the installation instructions they definitely helped me.
