Quoted from gdonovan:3) Top left plastic.
The top left plastic is almost always broken or damaged on Flash Gordon. Here is a link to an overseas company that offers just that plastic. I’m not sure at the end of the day if it’s better to just buy a whole set to have the spare set of plastics from CPR, or buy this. However, I did stumble across this sometime ago.
