I will chime in here, like Czeckman and truckernix said. It is a real PITA to do. Look at all of the soft parts. If any of them look worn or are questionable replace them. I did my 52 last year, and you have to disassemble the whole door. Take pictures, measure, and don't throw anything away. You have to remove the vent glass assembly to get the window glass out. The shop manual is invalueable here. I purchased laminated glass locally and had it cut (take the old piece as a pattern) Tell them you want the edges beveled, also ask for the setting tape they just gave me the tape free gratis. It is a lot cheaper than buying glass online. If you do go with saftey glass it is thinner, and you either need thicker setting tape or have to use ureathane rubber setting caulk. One other note go slow and things will go well, also do a search and read up on the methodology. There is a wealth of tips and tricks in the archive.
