Thanks, the photo helps. Looking at your photo, the top edge of the case is also chipped/cracked so I need to replace that also. I purchased a complete unit from AF1 Racing. I'll use the lens and housing from that. My issue now is extracting the black screw from the housing. Is there a specific metric tool to use? I don't want to mangle the screw head. And, does it turn clockwise, or counterclockwise. I'm probably making this harder than it is, but I find being 85, I question just about everything I attempt. I'm still beating myself up for dropping the bike. Once the light is fixed, I'm selling the bike. It's time for me to live with my memories of almost 70 years of riding. Again, thanks for your assistance.
