Here are a couple of pictures from my alternator adventure.
I tried using super glue to glue the retaining nut on the back of the alternator without success. Looking back something like JB Weld (epoxy) would have worked better.
Once I got the alternator into the position below, I was able to slide the rear retaining nut (by the lip) along alternator body and then hold it in position with an ice pick (or long slender screwdriver), until I could start the thread.
I can say with all certainty that if I didn't have some wire to hang the alternator into various positions during installation, that I would still be working on it.. LOL
Here's a picture after I got the retaining nut started..
