Easy fix. I did this fix on mine after inspecting if when it arrived. I used high heat epoxy and it has held for years.

Pretty sure one side of mine was cracked or missing... I left as is.

If it is the one holding a certain piece of the black plastic, it will noticeably sag if the whole piece is not there.

Good point, I think it was cracked then. But these are good ideas.

Isn't that an interference spot to go over the crash structure that you wouldn't want to make too thick?

The piece of fiberglass is extremely thin, maybe 3-4 mm wide, not to sure, but very thin and brittle, and anyone pushing force on the radiator vent will crack one if not careful. Wirewheels decided to ship mine already broken and I did a repair on it. This piece just hangs over the radiator, thickness would not matter I don't believe.

Best thing would be to cut a very small peice of fiberglass, double fold it, put some resin on it and place it over (after removing the broke piece). You cant see this area unless you take off the radiator vent.
