Matt - If I end up doing this myself, I'll let you know what I run into. I also have a new windshield to install so I'm thinking about having the alpine windows done at the same time. But I'll do them myself if I can't find someone experienced in doing them - I can screw them up myself just as well
Regarding the rear windows, I did those a while back. It's been a while, but I recall there being some rivets that need to be drilled out to get the frame apart. I actually removed the windows completely from the body, and replaced all of the rivets that hold the frame to the body with screws/washers/nuts. I did this because I had the windows try to pop out from the body when several rivets failed during a run down a washboard road.
