Just cleaned the Roadster and the front number plate plinth was loose

Took it off and the whole of the back where it mounts in front of the rad had broken away , the other side is cracking too.

Looks like its a moulded plastic item but the thinest bit of plastic is where the mounting holes are.
I think it can be repaired with some bits of bent metal, nuts , bolts platic padding etc

Has anyone else had a similar problem?
