while trying a few steel items to use for a bucking bar to complete the end rib rivets near the trailing edge, which does not have enough room for a normal bucking bar, I decided to modify my tungsten bucking bar so I could use it in tight quartes such as near the trailing edge. I ground down one corner leaving a 3/16" extension, and then smoothed out with scotchbrite wheel. This worked very well for the trailing edge rivets on the practice kit.
