Thanks for the tips guys. I don't have a ton of free time, and I'm already spending said time on repairs. So I was hoping to just find something I could bolt into the same holes (maybe even something designed for a RE), but I guess it's just not that simple.
@AgentX: I know it's technically a "classic" light/plate holder, but it just looks wrong with the new lights. The original lights had a cheap, modern, plastic look to them that I simply didn't like. I also plan to replace the controls with simpler, less plastic-y ones, perhaps with the vintage control kit that nfield gear offers. All that plastic just bothers me, haha.
