the bottom of my headunit?
relax buddy, they are illegal in australia, but they are not illegal in sweden, where the laws are way more stringent and geared towards safety, i couldn't even have a custom made exhaust manifold for my old volvo 240 because there were worried that without it being properly made it could be a safety risk...
then again, over there in the middle of winter, hot oil going everywhere doesn't sound like such a bad thing.
regardless, it's my car.
