Oh, my bad. I thought you were riviting the spring mount bracket to the frame and could not figure how you could do that
One thing I forgot to mention is that riviting something together eliminates part to part movement as the rivit expands to fill the loose fit in the holes. So, if you bolt something together it is best to clamp the parts together then drill one hole so that the bolt (asume 3/8") will just fit the hole. Then install the one bolt and clamp it down tight. Do the same for each successive bolt until you have the part fully attached. This method will help ensure the part is not realying on clamping fiction to keep it from sliding around.
