I have not yet installed the windshield. Waiting for my glass guy to do that. But I did read about installing the bolts upside down and when you look at all the clutter with the a/c and heater box, I am still wondering how you do that?? I don't think I am going to be removing my dash again, so I went with the easy bolt install which was as shown in the photos. Before the windshield goes in.
