Superglue would not be a good choice because it needs tight contact between both parts to have any strength. JB Weld is strong and will easily fill voids. Other waterproof relatively viscous epoxies should also work well.
Unfortunately, I made the repair in the driveway at night and did not think about trying to take photos. Also, I had to work fast to get enough JB Weld in place before it started to cure.
