I need to remove the fender stays but the heads of the bolts that hold the clamp for the stay at the fender are hidden behind the rear reflector. I didn't want to start pulling at the 50+ year old rubber mount for the reflector before asking for advice. Here's what I'm looking at. On the photo of the inside of the fender, those are the threaded ends of the bolts protruding through the clamp and the bolt heads are on the outside of the fender but hidden behind the reflector. What is the correct method for removing the reflector so that I can access the bolt heads?>
