OK here is the story. we have an 81 yr old civic and we put a new engine in it and well the exhaust manifold that we had in the old car doesn't work So we are trying to find one that will. I live in Missiouri and in need of some advice on where I can find old honda parts and then find the right one. I have a picture of the engine and where the manifold would be but when I look at the picture I don't know what to look for so if anyone can help I would really be thankful thank you
