rear body mount question

The rusted out steal body ('59 cj5) I'm replacing with fiberglass is missing some much needed information. What do the 4 body mount holes on the rear crossmember line up with? Is it just a lip on the under side of the tub or is there some kind of bracket or detail to receive the bolt?

thanks

 

There are typically 4 body brackets spot welded to the body. Take a look at my build thread: http://www.earlycj5.com/forums/showthread.php?t=77295 About half way down (April 2009), you'll see my damaged 4 mounts after they were removed, and the repair angles I used to mount the body.

 

Funny. That's almost exctly how I was thinking of dealing with it. But I'm thinking about glueing (3m 5200 marine adhesive) the angle to the back side of the tub to hide fasteners. The angle would also stiffen the area arround the tailgate opening.
