Rear Leaf Spring Hanger Bracket

[jmking9]

I'm in the process of trying to return my 72 Blazer 4wd to stock. The PO cut off all of the rear spring hangers and crudely bolted something out of another vehicle in. I'm getting rid of all of their stuff and putting on oem brackets. Is this all there is to the most rearward hanger (other than the shackle)? I ask because I can see that there were two rivets and some kind of bracket on the underside of the frame in the same area these go. I'm trying to figure out what's missing. If anyone has a picture from underneath of what that area should look like, I would really appreciate it. Thanks
