some B**tard of a child kicked both of my wing mirrors off yesterday night, luckily only the plastic casing came off the drivers side, but the passenger side was hanging off!! all i need to do to put it back on is compress the spring, and push the cap thing back on. dont know if anyone knows wot i'm on about (will put picks up when i get chance). but anyway, just want to no if it is possible to compress the spring by hand of would i need some sort of tool? or should i just cut my losses and buy a new mirror??
