I've done this conversion to my '74, and it rocks! It really helps reduce interior temps on hot days (no A/C). The list wrc3 posted is pretty much it, with the exception of various bolts. Try to find a window that has a good seal between the glass and frame. It material can dry and crack, causing leaks, especially from the lower corners. Also, I recommend using the black weatherstrip adhesive, which you'll probably have to order. Most auto parts stores seem to only stock the yellow. Have a roll of duct tape handy - you'll need it to help hold the gasket in place until the adhesive sets. I warmed my gasket up by letting it sit in the hot sun for a while, to help with fitting it in place. It is a real pain to install, but with patience and persistance, you can do it, and leak-free to boot. If you get a storage tray, make sure it has the hinges, too. Two items I can't find anywhere are the hinge mounting brackets that rivet to the rear body, and the clasp bracket that the tray's latch snaps into. I plan on making these pieces myself in the next couple of weeks. For now the window merely resides on the cargo area floor. One last thing that might be helpful would be the page fom the factory assembly manual. it will show all the necessary parts and their relative moutning points. No holes had to be drilled. Good luck!
