Before you drill holes and zip tie stuff together, remember all the cool stuff you can do with epoxy and fiberglass. West System Epoxy has some excellent tutorials online and most of the broken tabs can be recreated with fiberglass. You can look at my bike, no visible damage to the plastic yet there are very few places that have not been repaired. I even reproduced the mushroom shaped pins that push through the rubber grommets to hold on the side panels. Fiberglass is tough stuff. Its stronger than the plastic you are repairing. The broken tab on that lower fairing section connecting the right and left sides is a perfect example. You can recreate that tab using the other side as a model. You can drill it, file it, sand it, paint it. What's not to like ?
