This might look like an artifact from the Titanic, but in fact it is the part of the exhaust that the muffler hanger fastens onto. My problems are that the original screw is rusted completely, and the head is broken off (bottom of the pic) - also, the new hanger I have doesn't really engage very well with the top part, due to the severe rust. This is a 1978 California bus, so it has a cat and (from what I've been told) a kind of rare straight exhaust pipe from the heat exchangers to the cat (which is what this picture is a part of).
Any suggestions? I've thought of trying to drill out that screw and then use a nut/bolt combo to hold the muffler hanger, as well as try to clean out the top part so the hanger will fit snugly. Or can I just replace this piece? I'm not sure if it's part of the whole straight pipe. Or has anyone else faced this problem and used a different kind of muffler hanger?
Thanks!
