Exhaust backbox mounting bracket bolts!
over the last two weeks I've had a banging noise coming from the rear passenger side of the car which sounded like metal hitting metal. I finally got round to getting under the car on Saturday to see what it was and Ifound that one of the bolts for the backbox mounting bracket had fallen out!
From looking at the hole where the bolt has come out of I cant tell if it has a thread inside or whether I need a nut on the other end. I'm unable to get my hand round the other side to have a feel either! I've temporarily fixed the knocking with a trusty old cable tie but would obviously like to get a proper bolt sorted ASAP.
Does anyone know what size bolt this should be and whether a nut needs to go on the other end of it or if the hole will be threaded?
