It's relatively easy to do it by yourself. I just finished mine yesterday. The biggest issue and concern I had was getting the glass into the rubber channel. I used masking tape to hold it into place until I got it secured. I used a plastic tool with the rounded end like the one jockbolter50 showed in his pictures to get the rubber spline worked into the groove to lock everything in place. I would not recommend using any metal tool to do this as it is likely going to eventually slip and you wouldn't want to scratch your paint or the glass. I did not have the spreader tool like he also showed that is similar to the one shown in the shop manual. Another important thing is to use plenty of rubber lubricant. Soapy water would probably work, but I used a product I got at NAPA called RuGLYDE. I recommend lubricating a few inches at a time and just go slowly.
