Thanks columbiA but I am still confused. Is it the spare tire bracket stud #2100 that goes in the large (1") top hole in the body? How many bracket stud nuts are needed for the stud and what is the order of assembly? This is probably very easy but I am just not seeing it.
A long bolt passes thru the outer panal and brace, and threads into the upper threaded hole in the spare tire bracket. If it is a rumble seat car, you have a square hole in the curved inner panal where you can see the head of that bolt.
Here's another picture (courtesy of Marco T. I think) that shows the two required brackets - one attached to the curved inner panel and the other attached to the rear outer panel. The rumble seat models were done this way - not sure if the trunk models used both braces or not.
