/diy/ - Do It Yourself

In this pic, I just replaced those two block things. The top piece is OEM; Its 2 bolts connected by a thin piece of metal at one end. Both bolt ends go into those two blocks, and nuts are screwed onto the other side. The two blocks don't have holes in the exact position as the OEM blocks, and the OEM dual-bolt connector thing is bent, so I don't really have a way to use it.
What can I replace that dual bolt thing with? It connects the front plastics of a motorcycle (headlights, windshield, etc) with the frame, so I'm not sure if two regular bolts and two nuts are secure enough. No room for a big wrench or torquing, if that matters. Does that thin piece of connecting metal help with keeping everything tight or prevent spinning?
