Hello, ive got a couple of problems with my corrado following the winter rest that I was hopeing someone might be able to shed some infomation on. 1st is that over the winter the active rear spoiler has stopped popping up at 60mph automatically, you can still move it by the switch manually but nothing automatically. 2nd is that over the winter the fuel filler point has become very rusty where you screw your filler cap onto and requires replacing, I didnt know if this is a part that can be found or if anyone has one there willing to sell and also is it better to get a fuel tank and neck as it
