Both parts are not in production since 2008.
Hinges in my sets are in various conditions, some of them are way too loose to my liking. No ones fault, I was active kid who built a lot. But now it's like 10 years too late to replace them with new ones. Or is it? I'd prefer original Lego brand replacement that can be used without changing anything else in building instructions, but other ways to replace them are welcome, too. Restoring the ones I have is another question (that probably was already asked).
