Hello, I don’t know if I’m right here in this forum with my question but where exactly can I buy a new screw for the camshaft wheel of an Opel Corsa B 1.4 60 hp? I’ve already looked everywhere and found nowhere a new screw for the camshaft wheel. I have to change the thermostat on Saturday and this is unfortunately exactly behind the cover, which I can only get off when I unscrew the camshaft wheel. As far as I know, you have to use a new screw n but I don’t know where to buy a new spare screw. I’m grateful for any help
