Ski locker crack repair?

Anyone had to repair a cracked rear ski locker insert? The plastic on mine is cracked around the 90* bend from mounting flange and the storage well. It has gotten bad enough I need to do either repair it or replace with something else. Not sure how to attempt it. Glass and resin? I used a product called plast-aid (https://www.plast-aid.com/) in the past to bond interior panels in cars and it worked well for that non-structural purpose, though they say you can reinforce it with fiberglass tape which may be the ticket if there's not a better product for this.

I haven't had to but epoxy & glass should do the trick. They make heavier cloth called woven roven that's really beefy. Would probably need to cut woven into strips when laying it up cuz it doesn't like to bend tight corners. Even a lighter cloth should work. On a smaller repair epoxy makes sense. Easier to use than poly resin although more expensive.
