Barracuda quarter glass

You can access the mounting bolts through holes in the inner body wall. You might have to run the window up/down to get access to the bolts.

I last did that in about 1992. I was a sophomore in high school...replaced the window on my own. As I recall, you take out the rear seat back strap (two phillips screws), the aluminum trim (several screws), crank handle, and the trim panel.
