As with everything you have to feel comfortable with taking it on especially when this is something everyone will see. Also is your intent for the car to be a daily driver or a show car? That being said I did mine about 15 years ago, and acted like "How hard can this be?", but on the inside I was freaking out.

If you take your time, look at your old top, take some pics (back in the days of the Polaroid Instamatic), etc. it is not that hard. I put mine out in the sun the day before to help smooth out the fold marks from the box it came in. I also put it out in the sun for a few hours before trying to put it on to make sure it was nice and flexible. A second set of hands is nice to get everything laid out. Just check everything as many times as it takes for you to be comfortable before you make that 1st hole or trim any off by the bow. The site info is great, I wish I had it back then, all I had was a 3" x" 5" typed paper that had generic info. You can also trace the outline of your old top w/ chalk to use as a reference, but remember that it is only a reference!!! I accomplished what I needed it for, a top that looked ok from 5ft and kept the rain out. Most of the time the top is down anyway. I didn't use the springs that ran through the window posckets, mainly because they were not on the car to begin with. It's been fine without them so far. Figure on spending a good day on it, and when you finish in about 4-5 hours, sit back grab a cold one and admire the job YOU did.

Good luck
