Those are a given.. you are lucky it was one...Actually I replaced all mine on my Spider S2 rear bumper.. How? 1) slide out the plate 2) take a socket out of your tool drawer that is larger than the head of the broken bolt and place it over the head. 3) insert this combo in the jaws of life your vise and press the broken stud through the plate using the socket as your catcher when the bolt releases the mini tack welds holding it on. .. sounds like a .22 shot and takes little pressure. .. 4) my 5mm hole left in the plate was tapped to 6 mm and all SS 6 x 1 threaded in and are better than was. now you owe me me twice today.
